Problemas en el análisis de metilsiloxanos volátiles (VMS): origen y soluciones

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 microextraccion (HS-SPME) have been applied for the analysis of VMS in environmental samples. Alternatively, solvent extraction combined with large volume injection...
