General Certified Reference Material Notes
Expiration Notes:
·
Expiration date of the unopened ampul stored at the recommended storage condition is the last day of the month listed in
the expiration date field.
·
Uncertainty, concentration, and expiration of the CRM are based on the unopened product being stored according to the
recommended condition found in the storage field.
Purity Notes:
·
Purity and/or chemical identity are determined by one or more of the following techniques: GC/FID, HPLC, GC/µECD,
GC/MS, LC/MS, RI, and/or melting point.
·
Compounds with a listed purity of less than 99% have been weight corrected to compensate for impurities and/or salts.
A correction factor is used to calculate the amount of compound necessary to achieve the desired concentration of the
parent compound in solution.
·
Purity of isomeric compounds is reported as the sum of the isomers.
·
Purity values are rounded to the nearest whole number.
Certified Uncertainty Value Notes:
·
The uncertainties are determined in accordance with ISO Guides 34 and 35. The certified combined stressed uncertainty
value ( includes gravimetric uncertainty, homogeneity between-ampul uncertainty, storage stability uncertainty and
shipping stability uncertainty and were combined using the following formula:
k is a coverage factor of 2, which gives a level of confidence of approximately 95%.
·
·
It is important to note that the shipping stability uncertainty was obtained under temperature extremes for specific time
intervals; therefore, the certified combined stressed uncertainty value should only be applied to the product if it was
stored at non-standard temperature conditions up to and including 7 days. Contact Restek Technical Service at
www.restek.com/Contact-Us for use recommendations if your shipment was in-transit for more than 7 days at nonstandard temperature conditions.
Apply the certified combined unstressed uncertainty value if the product was received under standard shipping
conditions. Apply the certified combined stressed uncertainty value if the product was received under non-standard
conditions as specified below.
Label Conditions
Standard Conditions
Non-Standard Conditions
25°C Nominal (Room Temperature)
< 60°C
≥ 60°C up to 7 days
10°C or colder (Refrigerate)
< 40°C
≥ 40°C up to 7 days
0°C or colder (Freezer)
< 25°C
≥ 25°C up to 7 days
·
Separate (not combined) uncertainty values for gravimetric uncertainty are also displayed on the certificate, if needed,
separate homogeneity between-ampul uncertainty, storage stability uncertainty and shipping stability uncertainty values
are available by contacting Restek Technical Service at www.restek.com/Contact-Us.
·
The packaged amount is the minimum sample size for which uncertainty is valid. The ampules are over-filled to ensure
that the minimum packaged amount can be sufficiently transferred.
Manufacturing Notes:
·
Concentration is based upon gravimetric preparation using either a balance whose calibration has been verified daily
using NIST traceable weights, and/or dilutions with Class A glassware.
Handling Notes:
·
Samples should be transferred into deactivated vials for handling and storage. Restek supplies deactivated vials along
with most standards packed in 2 mL ampules. Due to space constraints, Restek does not supply vials for larger volume
ampules. Restek sells DMDCS for the purpose of glassware deactivation as catalog number 31840, which includes
complete instructions. Restek will also deactivate larger volume vials from our inventory as a custom ordered item.
Contact your Restek sales or customer service representative for details.
·
If any undissolved material is visible inside the ampul, sonicate the unopened ampul until the material is completely
dissolved.
