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.
