02. Fourier Transform Infrared analyzer - 700 FTIR

The 700 Series FTIR Analyzer delivers fast, accurate analysis of virtually any gas that has an infrared absorption spectrum. 


More details

The California Analytical Instruments 700 FTIR Analyzer provides fast, continuous and stable analysis of virtually any gas that has an infrared absorption spectrum. The proprietary heated sample cell enables the instrument to accommodate hot samples containing high levels of moisture. The 700 FTIR can serve a variety of analytical applications, including diesel emissions, CEM monitoring, ammonia slip, SCR inlet/outlet monitoring, process monitoring and others. Unlike other FTIR analyzers, the 700 FTIR does not require liquid nitrogen, eliminating the need to constantly fill LN2 dewars and the associated safety issues. Its small footprint and light weight allow easy installation and transportability when required.
