CAI Introduces New Fourier Transform Infrared Analyzer

January 31, 2011

Orange, CA (January 31, 2011) - California Analytical Instruments, Inc. announced today the new 600/6000 Series FTIR, which provides fast, continuous and stable analysis of virtually any gas which has an infrared absorption spectrum. Unlike other FTIR Analyzers, the 600 Series FTIR does not require liquid nitrogen thus eliminating the need to constantly fill LN2 dewars with associated safety and cost issues.

The standard 600 series FTIR offers high sensitivity with a long path multi-reflection gas cell (effective path length of 4.3 meters) and has the versatility to be heated to either 50°C or 191°C depending on the application.

The 600-SC FTIR offers a low volume/low flow system that is heated to 50°C. Flows can be as low as 50 sccm. Options include a fuel cell O2 sensor and an internal sample pump.
