Determination of Carbon Monoxide in Air by Triple Quadrupole Mass Spectrometry.
Abstract
Carbon monoxide has been determined at parts-per-million concentration in the presence of carbon dioxide, nitrogen, and hydrocarbons by triple quadrupole mass spectrometry (TQMS). In this work, advantage is taken of the ability of TQMS to distinguish differing ions of the same mass. The first quadrupole mass filter selects m/z 28; these selected ions undergo collisionally activated decomposition in the RF-only quadrupole collision cell and the CO+ product ion at m/z 12 is mass filtered by the third quadrupole and detected. Quantitation of the CO concentration is achieved by the addition of a known amount of labeled internal standard, 13CO, which displays a fragmentation peak at m/z 13 when the first mass filter selects the parent at m/z 29. Side-by-side comparison with the m/z 12 peak from CO allows the determination of CO concentration to within 20% down to 10 ppm. (Author)
