At Trace Analytics, we use a gas chromatograph-mass spectrometer (GC-MS) to analyze gases such as carbon dioxide, carbon monoxide, gaseous hydrocarbons, halogenated hydrocarbons, helium, methane, nitrogen, nitrous oxide, oil vapors, oxygen, total volatile hydrocarbons, and volatile organic compounds such as alcohols, halogenic hydrocarbons, esters, esters/ ether alcohols, ketones, aromatic/ alfatic hydrocarbons.

The samples are collected in 20 mil glass vials or charcoal tubes. The GC-MS shown in the video uses an auto-sampler to process the glass vials. The computer is programmed to run 23 daily calibration standards, 3 calibrations every 10th sample, and the individual analysis requirements for each glass vial.

Although the "real work" is done inside the GC-MS, we thought you might enjoy seeing how the autosampler processes the source and ambient bottles from your AirCheck samples.
