An American National Standard Designation: D 6729 – 04e1 Standard Test Method for Determination of Individual Components in Spark Ignition Engine Fuels by 100 Metre Capillary High Resolution Gas Chromatography1 This standard is issued under the fixed designation D 6729; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. e1 NOTE—Corrected 6.3 editorially in March 2008. present. Samples containing significant amounts of olefinic or naphthenic (for example, virgin naphthas), or both, constituents above n-octane may reflect significant errors in PONA type groupings. Based on the gasoline samples in the interlaboratory cooperative study, this procedure is applicable to samples containing less than 25 mass % of olefins. However, some interfering coelution with the olefins above C7 is possible, particularly if blending components or their higher boiling cuts such as those derived from fluid catalytic cracking (FCC) are analyzed, and the total olefin content may not be accurate. 1.4.1 Total olefins in the samples may be obtained or confirmed, or both, if necessary, by Test Method D 1319 (volume %) or other test methods, such as those based on multidimensional PONA type of instruments. 1.5 If water is or is suspected of being present, its concentration may be determined, if desired, by the use of Test Method D 1744, or equivalent. Other compounds containing oxygen, sulfur, nitrogen, and so forth, may also be present, and may co-elute with the hydrocarbons. If determination of these specific compounds is required, it is recommended that test methods for these specific materials be used, such as Test Methods D 4815 and D 5599 for oxygenates, and D 5623 for sulfur compounds, or equivalent. 1.6 Annex A1 of this test method compares results of the test procedure with other test methods for selected components, including olefins, and several group types for several interlaboratory cooperative study samples. Although benzene, toluene, and several oxygenates are determined, when doubtful as to the analytical results of these components, confirmatory analyses can be obtained by using specific test methods. 1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. 1. Scope* 1.1 This test method covers the determination of individual hydrocarbon components of spark-ignition engine fuels and their mixtures containing oxygenate blends (MTBE, ETBE, ethanol, and so forth) with boiling ranges up to 225°C. Other light liquid hydrocarbon mixtures typically encountered in petroleum refining operations, such as blending stocks (naphthas, reformates, alkylates, and so forth) may also be analyzed; however, statistical data was obtained only with blended spark-ignition engine fuels. 1.2 Based on the cooperative study results, individual component concentrations and precision are determined in the range of 0.01 to approximately 30 mass %. The procedure may be applicable to higher and lower concentrations for the individual components; however, the user must verify the accuracy if the procedure is used for components with concentrations outside the specified ranges. 1.3 The test method also determines methanol, ethanol, t-butanol, methyl t-butyl ether (MTBE), ethyl t-butyl ether (ETBE), t-amyl methyl ether (TAME) in spark ignition engine fuels in the concentration range of 1 to 30 mass %. However, the cooperative study data provided sufficient statistical data for MTBE only. 1.4 Although a majority of the individual hydrocarbons present are determined, some co-elution of compounds is encountered. If this test method is utilized to estimate bulk hydrocarbon group-type composition (PONA) the user of such data should be cautioned that some error will be encountered due to co-elution and a lack of identification of all components 1 This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products and Lubricants and is the direct responsibility of Subcommittee D02.04.0L on Gas Chromatography Methods. Current edition approved Nov. 1, 2004. Published November 2004. Originally approved in 2001.

Apparatus 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 6.1 Gas Chromatograph, a gas chromatograph equipped with cryogenic column oven cooling and capable of producing repeatable oven ramps from 0° to at least 300°C is required. The following features are useful during the sample analysis phase: electronic flow readout, electronic sample split-ratio readout, and electronic pneumatic control of flow. Though their use is not required, careful review of this test method will demonstrate the usefulness of a gas chromatograph equipped with these features. These features will replace the need to carry out the manual calculations that must be performed as listed in 8.1 and 8.2. 6.2 Inlet—a capillary split/splitless inlet system operated in the split mode is recommended. It must be operated in its linear range. Refer to 8.4 to determine the proper split ratio. 6.2.1 Carrier Gas Pneumatic Control—Constant carrier gas pressure control was used by all cooperative study participants. This may be either direct pressure to the inlet (injector) or by using a total flow/back pressure system. 6.2.2 Pneumatic Operation of the Chromatograph—The use of constant pressure was the mode of operating the gas chromatography used by the participants in the interlaboratory cooperative study. Other carrier gas control methods such as constant flow (pressure programming) may be used, but this may change the chromatography elution pattern unless the temperature programming profile is also adjusted to compensate for the flow differences. 6.2.3 Temperature Control—The injector operated in the split mode shall be heated by a separate heating zone and heated to temperatures of 200 to 275°C. 6.3 Column, a fused silica capillary column, 100 m in length by 0.25 mm inside diameter, coated with a 0.5 µm film of bonded dimethylpolysiloxane. The column must meet the resolution requirements expressed in 8.3. Columns from two different commercial sources were used in the interlaboratory cooperative study. 6.4 Data System, a computer based chromatography data system capable of accurately and repeatedly measuring the retention time and areas of eluting peaks. The system shall be able to acquire data at a rate of at least 10 Hz. Although it is not mandatory, a data system which calculates column resolution (R) is extremely useful as it will replace the need to carry out the manual calculations which must be performed as listed in 8.3. 6.4.1 Electronic Integrators, shall be capable of storing up to 400 components in the peak table and shall be able to acquire the data at 10 Hz or faster speeds. They shall be capable of integrating peaks having peak widths at half height which are 1.0s wide. The integrator must be capable of displaying the integration mode of partially resolved peaks. In addition, these integrators should be able to download a commonly readable format of data (that is, ASCII) to a computer in order to facilitate data processing. 6.5 Sample Introduction—Sample introduction by way of a valve, automatic injection device, robotic arm or other automatic means is highly recommended. An automatic sample introduction device is essential to the reproducibility of the analysis. Manual injections are not recommended. All of the 2.

Terminology 3.1 Definitions—This test method makes reference to many common gas chromatographic procedures, terms, and relationships. Detailed definitions can be found in Practice E 355. 4. Summary of Test Method 4.1 Representative samples of the petroleum liquid are introduced into a gas chromatograph equipped with an open tubular (capillary) column coated with the specified stationary phase. Helium carrier gas transports the vaporized sample through the column, in which it is partitioned into individual components which are sensed with a flame ionization detector as they elute from the end of the column. The detector signal is recorded digitally by way of an integrator or integrating computer. Each eluting component is identified by comparing its retention time to that established by analyzing reference standards or samples under identical conditions. The concentration of each component in mass % is determined by normalization of the peak areas after correction of selected components with detector response factors. The unknown components are reported individually and as a summary total. 5. Significance and Use 5.1 Knowledge of the specified individual component composition (speciation) of gasoline fuels and blending stocks is useful for refinery quality control and product specification. Process control and product specification compliance for many individual hydrocarbons may be determined through the use of this test method. 2 For referenced ASTM standards, visit the ASTM website, www.astm.org, or contact ASTM Customer Service at [email protected].

The linear dynamic range of the detector should be 106 or better. The detector is heated to 300°C. where: F = r = L = = Pi Po = Pref = T = Tref = µ = 7. Reagents and Materials 7.1 Calibrating Standard Mixture—A spark ignition engine fuel standard of known composition and concentration by mass can be used. In order to corroborate the identification of the sample, a typical chromatogram (Fig. 1) was obtained from reference sample ARC96OX.4 7.2 Gas Chromatograph Gases—All of the following gases shall have a purity of 99.999 % (V/V) or greater. split ratio 5 S 5 7.2.1 Helium—The test data was developed with helium as the carrier gas.

Tabulate for each split ratio the concentrations of the 10 to 15 components. Verify that for each component selected, its concentration does not vary by more than 3 %. (1) 8.1.3 The typical retention times for methane and linear gas velocity for helium are 6.5 to 6.8 and 24 to 26 cm/s, respectively. 8.2 Setting the Split Ratio—If the gas chromatograph is equipped with an electronic split-ratio readout device, set the split ratio to a sample split of 200:1. If the gas chromatograph is not equipped with an electronic split-ratio readout device, one must first calculate column flow rate and then proceed to calculating split ratio using Eq 2 and 3. column flow rate 5 F 5 (3) where: R = = tR2 = tR1 Wh1 = 8. Instrument Check Out Prior to Analysis 8.1 Setting: 8.1.1 Linear Gas Velocity—If the gas chromatograph is equipped with an electronic flow readout device, set the flow to 1.8 mL/min. This is achieved by setting the carrier gas flow rate by injection of methane or natural gas at 35°C. Ensure that the retention time is 7.00 6 0.05 min. This corresponds to a linear velocity of 25 to 26 cm/s. This is equivalent to retention times of methane at 0°C ranging from 6.5 to 6.8 min. 8.1.2 If the gas chromatograph is not equipped with an electronic flow readout device, calculate the linear gas velocity in cm/s using Eq 1. ~60 p r2!

Procedure 9.1 Set the operating conditions of the gas chromatograph as shown in Table 1. These conditions will elute all components up to and including pentadecane (nC15). 9.2 All of the parameters in Table 1 can be marginally changed to optimize for sample types and optimize for characteristics of each gas chromatographic system. The final boiling point of samples should not exceed nC15 and the (2) 4 Reference spark ignition sample No. ARC 960X obtained from the Alberta Research Council, Edmonton, Alberta, Canada.

Cool the sample to less than 4°C, maintain at that approximate temperature until the autosampler is loaded and analysis begins. 9.4 Preparation/Storage: 9.4.1 Samples Stored in Vials—Cool the original sample to less than 4°C prior to taking a sample aliquot or prior to filling column resolution (R) performance requirements listed in Table 2 should not be compromised. 9.3 Obtain a representative sample following the guidelines of Practice D 4057 and any other applicable guidelines. Take precautions to minimize the loss of light ends from volatile samples. The sample container may be cooled prior to transfer 4 D 6729 – 04e1 FIG. 1 Chromatogram for Reference Spiked Gasoline (continued) the sample vials. The sample aliquot container, or the vial, or both, can also be cooled prior to the transfer of the original sample. Syringes may also be cooled along with the sample for manual injections. 9.4.2 Samples Stored in Pressurized Containers—It is recommended that they be kept away from direct heat or light. No other sample preparations are necessary for samples stored in pressurized containers. Avoid storage at temperatures greater than 25°C. Store pressure containers in accordance with the manufacturer’s instructions. 9.5 It is recommended that a quality assurance (QA) sample similar to the reference material gasoline sample be run at 5 D 6729 – 04e1 FIG. 1 Chromatogram for Reference Spiked Gasoline (continued) regular intervals (see Fig. 1). An interval of once per week or after every 15 samples is recommended. The quantitation results use statistical quality control charts can track benzene. Other components of interest in the reference sample can be tracked in a similar manner. By monitoring these components over an extended period of time, the performance of the column and the chromatographic system can be determined. 6 D 6729 – 04e1 FIG. 1 Chromatogram for Reference Spiked Gasoline (continued) 10. Data Analysis 10.1 Compound Identification—Prepare a table listing all of the retention times of the components in the sample. Compare the retention time of each peak with that of the reference gasoline. Pay particular attention to the fact that columns can be overloaded, and peaks can shift in retention time. Observe the peak pattern so that proper identification is made by comparison with the reference material. 10.2 Consistency in peak identification can be achieved by using software (data handling software, spreadsheet software, and so forth). Alternatively, a retention index system can be used. 7 D 6729 – 04e1 FIG. 1 Chromatogram for Reference Spiked Gasoline (continued) 8 D 6729 – 04e1 FIG. 1 Chromatogram for Reference Spiked Gasoline (continued) 9 D 6729 – 04e1 FIG. 1 Chromatogram for Reference Spiked Gasoline (continued) 10 D 6729 – 04e1 TABLE 1 Chromatographic Operating Conditions, Column Requirements and Data Acquisition Requirements Chromatographic Conditions Requirements Injector settings Injector temperature, °C Split ratio Liner Injection volume, µL Detector settings FID detector temperature, °CA Gas flows Hydrogen, mL/minB Air, mL/min Nitrogen make up, mL/min Column oven settings Initial temperature, °C Initial time, min 1st ramp rate, °C/min Final temperature, °C Final time, min 2nd ramp rate, °C/min Final temperature, °C Final time, min 3rd ramp rate, °C/min Final temperature, °C Final time, minC Column Requirements Length, m Inside diameter, mm Liquid phase Film thickness, µ Pressure, psig Flow, mL/min Linear gas velocity, cm/s Data acquisition, Hz Total analysis time, min A B C 250 175:1 - 275:1 deactivated glass 0.2–0.5 300–350 30–40 300–450 30 0 15 1 50 0 2 130 0 4 270 0 100 0.25 100 % dimethylpolysiloxane 0.5 40–50 1.7–2.0 24.5 10–20 140–150 Set to 25–50°C above the highest column temperature.

The average relative response factors for the oxygenates were calculated from the study and are listed in Table A2.1. They have been incorporated into the IHA Method. The percent standard deviation of these relative response values was as high as 7 %. MTBE was the only oxygenate that was present in sufficient number of samples to meet the ASTM requirements for round robin testing in accordance with RR: D02-1007. Therefore the statistical data for MTBE should be taken from Table A1.2. where: RRFCH4 = relative response factor of each component with respect to methane (RRFCH4=1.000), = molecular weight of the component, i, MWi = number of carbon atoms in the molecule, and Nc MWCH4 = molecular weight of methane (16.04276). 10.4 Convert the acquired areas to corrected areas by multiplying each area by its corresponding relative response factor as indicated in the following equation.

HYDROCARBON DATA A1.1 Table A1.1 presents the component retention times and properties. A1.4 The precision statement for the olefins and cycloparaffins is determined by taking the square root of the value determined in the summary; multiply by the coefficient (rcoef) for repeatability and the coefficient (Rcoef) for the reproducibility. A1.2 Table A1.2 represents the repeatability and reproducibility precision estimates prepared by statisticians of CS94 in accordance with RR: D02-1007. The analyte qualification process for precision statements is outlined as follows: A1.2.1 For each analyte to qualify for a precision statement, it must be present in at least six samples, and detected by at least six laboratories, at least once, in accordance with RR: D02-1007 requirements. A1.2.2 The (repeatability standard deviation)/mean value for each analyte/sample combination must be less than or equal to 0.1, in accordance with LOQ requirements which, while not a standard, is what CS94 is recommending.

The statistics for the grouping are shown in Table A1.3 as an indication of reproducibility and repeatability of reporting the results as a group summary. However, there is a possibility that significant error could occur due to co-elution of peaks, the presence of significant amounts of olefinic or naphthenic constituents, or both, above octane and the percent unknown in the sample. If more accurate summary results are needed that are not covered by the above precision statement, for some or all of the above families of components, please consider another ASTM test method. A1.3 Summary for Oxygenates: Warning—The statistical data could be done on the oxygenates but there was not an equal number of all oxygenates in the round robin. MTBE was the largest contributor to the statistical results. The number of samples that contained each oxygenate is as follows: Oxygenate Type Ethanol t-butanol MTBE ETBE TAME rmin 0.0726 0.1555 Approximate Concentration Range 1 %, and 12 % .20 %, and 1.0 % 1, 2, 4, 4, 8 and 16 % 0.50 % 15.00 % 13 D 6729 – 04e1 TABLE A1.1 Component Retention Times and Properties NOTE 1—The names used are from several other tables and changes have been made where the GCMS did not agree with the peak name or its retention time.

NOTE 9—In some instances the chemical group is known, but the chemical structure is not known (for example, C6-olefin; the position of the double bond is not known). NOTE 10—Relative response factors for six of the major oxygenated compounds have been determined by using the average results from seven laboratories analyzing six samples in duplicate. These same samples were used to determine linearity of methanol, ethanol, t-butanol, MTBE, ETBE and TAME from a concentration level ranging from 1 mass % up to 30 mass %.

HYDROCARBON DATA USING HYDROGEN CARRIER based on a 35°C isothermal analysis of pentane (n-C5). X2.1 This appendix presents a modification of the test method that decreases the total analysis time from 150 minutes to 82 minutes. The primary change is the use of hydrogen rather than helium as the carrier gas. The oven temperature ramp and column flow rates are also modified in order to ensure optimum resolution and linear velocity. All remaining operating parameters of the GC remain as stated in the method. Column performance tests are included in order to evaluate method performance. This appendix includes a chromatogram with components identified, as well as the component list analyzed with the test conditions specified in Table X2.1. X2.6 Figs. X2.6-X2.11 presents, in detail, the identified CGSB0496 gasoline standard analyzed under the conditions stated in Table X2.1. X2.7 Table X2.4 presents the summary of coeluting compounds. X2.8 Table X2.5 presents the component retention times and properties of the compounds identified in the CGSB0496 standard. X2.9 All sections of Test Method D 6729 should be followed as written, except for the following: X2.9.1 In 7.2, hydrogen gas is used rather than helium as the carrier gas. X2.9.2 In 8.1, the Linear Gas Velocity is now set to 31.0 psi constant pressure that corresponds to an average linear velocity of 42 cm/s at 35°C. This linear velocity value is optimum for hydrogen. Under these isothermal conditions, methane should elute at 3.9 minutes. Using the conditions described in Table X2.1, methane should elute at 3.6 minutes. X2.9.3 The Table 1 chromatographic operating conditions are now modified as in Table X2.1. X2.2 Table X2.1 presents the chromatographic operating conditions, column requirements, and data acquisition requirements. These conditions will elute all components up to and including pentadecane (n-C15). X2.3 Table X2.2 presents the column resolution performance requirements. X2.4 Figs. X2.1-X2.5 present chromatographic examples of each critical separation described in Table X2.2.
