Abstract
Inspection of PET bottles for contamination is performed with a mass spectrometer in which the gas sample is ionized by an ionized primary gas. This causes greatly reduced fragmentation, or unambiguous fragmentation, of the gas sample. As a consequence, the spectrum obtained is very meaningful on its own, and can be interpreted very rapidly, which is an essential prerequisite for the use of mass spectrometers in industrial inspection.
