Fingerprinting techniques mass spectrometry, pyrolysis

With recent developments in analytical instrumentation these criteria are being increasingly fulfilled by physicochemical spectroscopic approaches, often referred to as whole-organism fingerprinting methods.910 Such methods involve the concurrent measurement of large numbers of spectral characters that together reflect the overall cell composition. Examples of the most popular methods used in the 20th century include pyrolysis mass spectrometry (PyMS),11,12 Fourier transform-infrared spectrometry (FT-IR), and UV resonance Raman spectroscopy.16,17 The PyMS technique...

If a simple qualitative identification of a plastic is all that is required then fingerprinting techniques discussed in Chapter 6 may suffice. Fingerprinting instrumentation discussed include glass transition, pyrolysis techniques, infrared spectroscopy, pyrolysis - Fourier transform infrared spectroscopy, Raman spectroscopy and radio frequency slow discharge mass spectrometry.
