Abstract:PROBLEMS IN THE ANALYSIS OF VOLATILE METILSILOXANES (VMS): ORIGIN AND SOLUTIONS. Volatile methylsiloxanes (VMS) are pollutants widely distributed in the environment due to its extensive uses and high volatility. The analysis of these compounds is commounly performed by gas chromatography -mass spectrometry (GC-MS), and it is dificult due to the presence of background contamination and volatile losses. Different preconcentration techniques such as purge and trap (P&T), headspace (HS) and headspace -solid phase … Show more
