The MultiGas™ 2030 is an FTIR based analyzer capable of ppb to ppm sensitivity for multiple gas species in a variety of applications, such as stack emissions monitoring, process monitoring, ambient air monitoring, purity monitoring, and selective catalytic reduction performance monitoring. The MultiGas 2030 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. The MultiGas 2030 collects high resolution infrared spectra which are analyzed using the quantitative spectral library.
