Make automated measurements of methane and non-methane hydrocarbons with the Thermo Scientific™ Direct Methane & Non-Methane Hydrocarbon Analyzer, Model 55i. Unlike instruments that measure only methane and total hydrocarbons, this back-flush gas chromatography (GC) system provides a direct measurement of non-methane concentrations.
Automated batch analyzer repeatedly collects and analyzes small amounts of the sample stream drawn in by the pump. Central to the instrument's operation is an eight-port, two-position rotary valve which is used to introduce the gas sample into the analyzer and to control the flow of gases through the chromatographic column. The proprietary column design is unaffected by the oxygen content of the sample and provides complete recovery of low volatility compounds while achieving absolute separation of methane from all C2 compounds.

PGD-100 prepares gas sample for the co-operating analyser by removing dust, salts particles and condensate, so the sample is dry and clean.
Using gas conditioner is essential in case of majority measurements with gas analysers.
Gas conditioner unit includes:
Gas probe pipe
Initial heated filter
Heated hose that supplies gas sample to the analyser’s drying module(s)
One or two drying modules
Final filters that cleans the dried gas sample
Gas pump
Condensation pump (only when PGD-100 is equipped with condensation type dryer with Peltier element)
Ventilation valve that provides clean air for cooperating analyser
Drying modules are: Nafion exchanger or condensation based unit.
The dryer receives adjustment settings from the co-operating analyser, and returns own status and errors to the analyser via RS-232 communication interface.
MD3 gas dryer was initially designed to be a part of our stationary maMoS analyser.
Though, thanks to the efficiency, small dimensions, and competitive price, MD3 dryer became interesting alternative and even dedicated solution as a standalone gas conditioner.
Its another strong point - universality, makes it available in two different versions: stationary (hung on the wall), and portable for “laboratory” applications.
GA-12plus hand-held analyser that can be equipped with up to 4 EC cells.
Larger cousin of GA-12 analyser that share very similar functionality and options.
Thanks to larger housing fits more sensors, is equipped with Li-ion battery by default.
Manufactured according to the principles of EN50379
Small in size, yet very skilful analyser – it has the best capabilities/price ratio. maMoS is our alternative for large, intricate CEMS systems, as it does not fall behind them concerning functionality and abilities, and is far ahead in terms of expenses.
It has modular construction, and many add-ons, that makes it easy to adjust to a very specific, individual application.
Powerful PC software allows to adjust many aspects of the work with the analyser very individually (work schedule, analogue outputs' behaviour, data presentations, and more...)
Cooper Environmental’s Xact® 640 is the first Multi-Metals Continuous Emissions Monitor to be proven successful for accurately measuring elemental concentrations in smoke stacks by capturing and measuring both particulate and vapor phase metals.
The Xact® 640 system uses reel-to-reel filter tape sampling and nondestructive X-ray fluorescence (XRF) analysis to monitor stack hazardous air pollutant (HAP) metal emissions. An isokinetic sub-sample of stack gas goes into the stilling chamber and then drawn through a chemically reactive filter tape. Vapor phase metals, including mercury, are deposited along with particulate-phase metals on the filter tape.
In 2007, the US EPA recognized the Xact® CEMS as an outstanding achievement in innovative clean air technology with a clean air excellence Award. In addition, the EPA approved the Xact® 640 as an alternative method for periodic Method 29 testing, feed stream analysis, and monitoring emissions during plant operation.
SCI’s Xact® 625i is designed for high time resolution multi-metals monitoring of ambient air, with detection limits that rival those of laboratory analysis. The Xact® 625i comes standard with a solid-state meteorological sensor and SCI’s proprietary ADAPT analysis package, making the instrument one of the most powerful air pollution source detection offerings in the industry.
The system uses reel-to-reel filter tape sampling and nondestructive energy dispersive X-ray fluorescence (EDXRF) analysis. The air is sampled through a low volume (16.7 l/min) particulate matter (PM) size-selective inlet and drawn through a filter tape. The resulting PM deposit is then advanced into the analysis area where the sample is analyzed by EDXRF for selected metals while the next sample is collected.
The ABB OA-ICOS gas analyzers build on the heritage and extensive track record of Los Gatos Research analyzers, using patented Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS) technology, the latest evolution in tunable diode laser absorption spectroscopy.

The use of the measuring principle of dynamic pressure
and PT100 assures a device which is easy in design
and operating as well as the realtime monitoring of the
measuring parameters.
The operating and display unit is integrated in the
weather protection casing. On the high‑quality display
all measuring values, status information and parame
ters are displayed.
Optionally, the absolute pressure at the measuring
point can be measured continuously by an absolute
pressure transmitter.
At the analysis of gas concentrations by the MGA 12 HR four different measuring methods are
applied:
- Infrared absorption
- Electrochemical cell
- Paramagnetic measuring method
- Thermal conductivity sensor
By the functional principle of infrared absorption, infrared gas components as CO, CO2, SO2,
NO, NO2 and CH4 can be detected simultaneously. This spectroscopic method is based on the
absorption of non-dispersive infrared radiation. The lessening of the radiation, which is
differing according to the wavelength, is a degree of the respective substance concentration.
For the measurement of O2 or H2S an electrochemical cell is used. The cell consists of a
non-porous fluororesin membrane and a solid integrated gold electrode. By the reduction at
the gold electrode, current is generated and converted to voltage by a thermistor. Thereby the
measured voltage is proportional to the concentration of the measuring gas component.
