The heart of the OMA-300 is the nova-II. Its diode array
contains 1,024 photodiodes, each designated to detect

data from all these diodes at each instant, the nova-II
continuously produces a full, high-resolution spectrum
of sample absorbance.

OMA-300 H2S ANALYZER
Analyte(s): H2S
Extensions: SO2, R-SH, COS, and/or NH3
Applications: natural gas, crude oil, syngas,
biogas, kerosene, stripped sour water...
Our most popular product in our most experienced application. The central consideration in
H2S measurement accuracy is the ability to correct for a volatile background spectrum; in providing analysis truly free from cross-interference,
the OMA-300-H2S stands alone.
OMA-300 CEM SYSTEM
Analyte(s): SO2, NOX, CO, CO2, and O2
Extensions: H2S, Cl2, COS, and/or CS2
No single technology is sufficiently versatile
to measure all of the chemicals targeted by
continuous emissions monitoring (CEM). The
OMA-300-CEM unifies three complementary
technologies—UV-VIS diode array (SO2, NOX),
infrared detection (CO, CO2), and tunable
diode laser (O2)—in one coherent system,
matching each chemical to its best detector.
OMA-300 CLEAN-IN-PLACE ANALYZER
Analyte(s): active ingredient of previous batch
Industries: pharmaceuticals, food processing,
dairy production, beverage production, biotech...
Clean-in-Place (CIP) is a method commonly used
to clean reaction chambers without disassembly. The OMA-300-CIP vastly reduces downtime:
instead of waiting for predetermined wash cycles
to be over, the system monitors effluent wash
solution, providing notification at the precise moment when the target chemical is eradicated.
OMA-300 CHLORINE ANALYZER
Analyte(s): Cl2
Extensions: ClO2, FeCl3, NCl3, TiCl4, vanadium, VOCl3
Applications: measuring EDC purity; titanium
dioxide pigment production; NCl3 control; VOCl3 in
organic synthesis; chlorine compound production
Seamless dynamic range from low ppm up to high
percent is achieved by the nova-II, which makes
automatic, real-time wavelength shifts to optimize
the light signal in step with volatile concentrations.

OMA-300 DeNOX ANALYZER
Analyte(s): NH3, NO, NO2, NOX
Ammonia slip downstream from NOX reduction
reactions indicates a host of problems (utility
waste, pollution, and ammonium bisulfate plugging). The OMA-300-DNX continuously monitors
the health of a DeNOX process stream, displaying
real-time concentrations of ammonia and NOX.
Unlmited alarms can easily be configured to
alert the DCS the instant that any concentration
thresholds are crossed.
OMA-300 SEMICONDUCTOR EDITION
Applications: CMP slurry, SC-1, SC-2, wet etching
(HF acid), SPM, metal ions, and more
The OMA-300-SE is designed to monitor chemical
composition in multiple streams, providing true
process transparency at several yield-critical junctures in semiconductor wafer production. Measuring up to 4 stream components simultaneously,
this system offers a new caliber of control in the
realm of fab chemistry.
OMA-300 COLOR ANALYZER
Scales: ASTM D-1500, APHA, Saybolt, Rosin, nonstandard, and multi-dimensional
In cases where stream color can serve as an indicator of product health, trust diode array detection.
Exploiting the broad spectrum, this system automatically shifts wavelength range to accommodate
absorbance changes in the stream; this explains
how the OMA-300-CLR never loses accuracy, even in
a process that ranges drastically from transparent to
near-opaque.

MICROSPEC
M O D U L A R A N A LY Z E R S
The MicroSpec format was developed as an expansion module for the OMA-300. Chemicals that have no distinct absorbance features in the ultraviolet-visible range (the domain of the OMA-300) require alternative detection methods;
we designed the MicroSpec modules to address these chemicals (O2, CO2, moisture, and more) with technologies like
infrared detection and tunable diode laser spectroscopy. The compact, single-analyte package excels both as a rugged standalone (with dedicated controller) and as a workhorse element within a larger integrated
system. The signature MicroSpec flow cell has a unique path length for each application.

The MicroSpec Series uses a 192x128 pixel backlit LCD screen as
a graphical interface. The main screen (at left) displays the live

buttons below the screen are used to navigate the GUI.
With the simple menus in the firmware, the user can easily
perform tasks such as assigning minimum/maximum concentrations for the alarm threshold and scheduling an auto-zero.

TA I L G A S A N A LY Z E R
The TLG-837 is AAI’s solid state, in situ solution for online tail gas analysis in sulfur recovery. This system monitors realtime concentrations of H2S and SO2 in the Claus process stream, computing the control parameter for a continuously
refreshed air demand signal.
The critical point of innovation lies in the sampling design. The patented, in situ demister probe condenses sulfur
vapor (the culprit of fouling and distortion) out of the process gas in a controlled manner, elegantly resolving the
major vulnerability of the typical tail gas analyzer. The lack of sample lines and heat tracing translates to extremely fast
response and low-maintenance performance.

THE APPLICATION
TLG-837 TAIL GAS ANALYZER
A critical step in refining crude oil
and natural gas is the removal of
naturally occurring hydrogen sulfide (notorious for its toxic, flammable, and corrosive properties).
Typically, an amine unit is used
to absorb H2S from fossil fuels.
The Claus process is the industry
standard for converting the “sour”
H2S-rich gas from the amine unit
into pure elemental sulfur, which
can be sold or stored.
This complete system provides continuous, real-time
measurement of the following analytes in a Claus process
tail gas stream:
• hydrogen sulfide (H2S)
• sulfur dioxide (SO2)
• air demand
• carbon disulfide (CS2)
• carbonyl sulfide (COS)
In the Claus process, H2S is combusted with oxygen:
3H2S + 3/2O2
SO2 + H2O + 2H2S
A catalytic converter reacts these
products to create elemental suflur
in its various crystalline forms:
2H2S+ SO2
2H2O + 3/XSx
The correct 2:1 stoichiometric
ratio of H2S to SO2 is necessary for
efficient conversion. As shown
by the combustion reaction, this
ratio is maintained by adjusting
the amount of available oxygen.
The efficiency of the Claus process
thus hinges on the reliability of the
air demand signal, a value calculated from real-time measurement
of H2S and SO2 concentrations in
the tail gas stream. An additional
concern is the detection of CS2
and COS, as the presence of these
compounds indicates potential
problems with the catalyst bed.
SULFUR VAPOR
Elemental sulfur occurs in the
Claus process stream as gaseous
S8 molecules. This sulfur vapor
distorts measurements and coats
optical windows. The TLG-837
probe completely neutralizes
the sulfur vapor problem using a
method unlike any other analyzer.
(See facing page.)
The TLG-837 uses nova-II diode
array detection technology (see
page 4) to simultaneously monitor
H2S, SO2, COS, and CS2 in the tail
gas stream and provide a continuously reliable air demand signal.

THE PROBE CONCEPT
(A) The Demister. Low-pressure steam is fed into the inner demister chamber, thus
cooling the length of the sample intake path. As gas from the process rises up the probe
body, this cooling effect forces incident sulfur to condense and drip back down to the
pipeline. The sample that reaches the optical flow cell is virtually sulfur-free.
(B) The Measurement. High-pressure steam is fed into a special channel in the probe
head to heat the optical flow cell. This prevents any sulfur that might have survived the
demister from condensing inside the flow cell and coating the lenses.
(C) The Return. An aspirator motivates the measured sample to exit the flow cell and
flow down the return line. A venturi effect is created by restricting the flow at the junction between the aspirator and the return line; this pressure drop is what continuously
cycles the sample. The exhausted sample is released back into the pipeline in the direction of the process flow.

Sulfur content in natural gas is an
oft-cited parameter for improving
product quality, distribution
networks, and pollution control. The
solid state TSA-100G continuously
monitors total sulfur compounds in
gaseous hydrocarbon streams.
The allowable sulfur content in diesel
is dropping steadily with pressure
from myriad interest groups. The
TSA-100L takes the pain out of
compliance, smoothly monitoring
total sulfur compounds in diesel
down to trace levels.
This system uses a pyrolyzer to
combust all sulfur compounds in
the sample to SO2; the oxidized
sample is fed into the flow cell,
where SO2 is measured by nova II
spectrophotometer (see page 2).
The TSA-100L prepares a sample with
precise fuel:air ratio, then gasifies
it by heating the mixing chamber.
A pyrolyzer combusts all sulfur
compounds in the sample to SO2. The
