Areas of Expertise - Air Separation and LIN, LOX, LAR

 
     
 

Our, fully validated, Thermo / Nicolet Fourier Transform Magna-IR 550 Series II systems are used routinely for qualitative and quantitative testing. A typical gas spectrum is illustrated below showing spectral characteristics for a Certified gas standard containing 5 ppm of acetylene, carbon monoxide, methane, and nitrous oxide, with 8 ppm carbon dioxide, leaving a margin suitable for quantitation at the ppb level.

The sections below list our standard analyses for Liquid Nitrogen (LIN), Liquid Oxygen (LOX) and Liquid Argon (LAR). Lower Limits of Quantitation (LOQ’S) may be obtained, if necessary, on a custom basis.
