QUANTITATIVE PYROLYSIS-GAS CHROMATOGRAPHY MASS-SPECTROMETRY AND PYROLYSIS MASS-SPECTROMETRY OF CHLOROLIGNOSULPHONIC ACIDS

The potential of quantitative pyrolysis-mass spectrometry is illustrat ed by two environmental applications of pyrolysis-gas chromatography-m ass spectrometry (Py-GC-MS) and in-source temperature-resolved pyrolys is-mass spectrometry (Py-MS). Py-GC-MS combined with selected ion moni toring (SIM) can give low-ppb detection limits for chlorolignosulphoni c acids, which are high-molecular-mass industrial contaminants in rive r water. Py-MS was used to quantitatively analyze sulphonic acid group s in macromolecular dissolved organic matter (DOM).
