Overview

MultiGas™ Analyzers are FTIR-based analyzers capable of ppb sensitivity for multiple gas species in a variety of applications, such as automotive emissions measurement, stack emissions monitoring, process monitoring, ambient air monitoring, purity monitoring, and selective catalytic reduction performance monitoring. The MultiGas™ Analyzer can perform analysis in gas streams that contain up to 40% water and can simultaneously analyze and display more than 30 gases. With permanently stored calibration spectra, the need for costly gas cylinders is reduced. In addition, operators will find the robust, fully automated MultiGas Analyzer easy to operate and maintain.

Field technicians are not required for routine maintenance, simplifying user serviceability
Simultaneous analysis of more than 30 gases
Permanent & transferable calibration spectra reduces the need for gas cylinders
10-100 ppb sensitivity for many toxic gases
Patented, linearized detector response assures all instruments maintain the same calibration
User-friendly software for simple operation by reduces the need for highly-trained operators

MultiGas™ Analyzer Innovations

The MultiGas Analyzer is composed of a 2102 Process FTIR Spectrometer, our patented, high-optical-throughput sampling cell, applications-specific analysis software, and an instrument independent quantitative spectral library. It collects high-resolution infrared spectra which are analyzed using the quantitative spectral library. This provides an accurate, highly sensitive measurement of most gases and vapors.

MultiGas software features multi-point calibration curves that provide a dynamic range up to 9 orders of magnitude (ppb to 100%). Calibrations for many species are provided with the instrument, and additional calibrations can be generated by the user from gases of known concentration. Utilities in the software verify the performance of each instrument, which allows a calibration generated on one MultiGas Analyzer to be used on any other MultiGas™ Analyzer without alteration.
