The Thermo Scientific model 70 FTIR Multi-Gas CEMS is a single analyser, continuous monitoring system capable of measuring up to ten gases for almost any incineration or co-incineration application
The new Thermo Scientific real-time monitoring system employs the most widely used, field-proven, process FTIR technology in the world for integrated stack gas monitoring systems.
Backed by Thermo Fisher's 25 years of experience as the leader in FTIR instrumentation, the model 70 FTIR multi-gas analyser possesses a high level of sensitivity, specificity, and dynamic range, with a dynamically aligned interferometer that provides exceptional long and short term stability.
The FTIR analyser uses a gas cell with a 5.2meter optical path.
Fitted with zinc selenide sample windows, the cell is suitable for elevated temperature conditions, operating reliably at temperatures up to 185C.
The Model 70's optical system is designed for a three-to-six month cycle of unattended operation, which significantly reduces operation costs.
In addition to the dynamically aligned interferometer, the pinned-in-place, pre-aligned components ensure permanent optical alignment, virtually eliminating method maintenance for uninterrupted operation and analysis.
The system's high-speed data analysis capability delivers extremely accurate, continuous gas measurement which is ideal for rapidly changing complex gas mixtures.
Compounds measured with the Thermo Scientific FTIR CEMS include carbon monoxide, nitric oxide (gas turbine), sulphur dioxide, hydrogen chloride, ammonia, water, nitrogen dioxide, nitrous oxide, hydrogen fluoride, methane, and carbon dioxide.
Also available from Thermo Fisher Scientific are two options for adding onto the system: a flame ionisation detector (FID) for monitoring total gaseous organic carbon and a zirconia oxygen analyser.
"Measuring ten or more gases with one analyser results in a substantially reduced cost of ownership," said Michael Nemergut, vice president and general manager for Thermo Fisher Scientific's Air Quality Instruments business.
"This expanded capability utilises an FTIR bench that has been the cutting-edge technology for the past 25 years, enhanced by our more than 35 years experience in stack gas emissions monitoring.
"The know-how and experience built into the Thermo Scientific model 70 FTIR CEMS makes choosing a multi-gas system easier than ever."
