Abstract
Flowing afterglow atmospheric pressure glow discharge mass spectrometry
(FA-APGD-MS) was used to interrogate different polymer species such as
biopolymers, synthetic homo-and co-polymers. The main advantages of
FA-APGD-MS for polymer samples include speed (< 30 s per sample) and
analysis at atmospheric pressures. Moreover, there are essentially no
restrictions as to the kind of polymer sample that can be analyzed
because FA-APGD-MS can deal with liquid and solid (soluble or insoluble)
bulk polymers and granulates, irrespective of their conductivity,
without requiring any sample preparation prior to analysis. We will
discuss the mechanism of ion formation as well as the limitation of the
accessible mass range (m/z < 500) in view of what type of information
can be gained from the mass spectra obtained. Monomer units and some
fragments were detected for homopolymers, e. g. cis-polyisoprene (IR),
poly(ethylene glycol) (PEG), poly(ethylene terephthalate) (PET), which
allowed identification
