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 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 2030 easy to operate and maintain. 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. This provides an accurate, highly sensitive measurement of most gases and vapors.
