Abstract
The increasing use of plastics in our society makes the vinyl chloride a potential source
of pollution for environment. Related to its toxicity and presence in the environment,
the new European Directive for drinking water quality includes now a limit for its
concentration in drinking water. Currently a government needs new analytical methods
to analyse this pollutant. This study concerns the optimization of the headspace
solid-phase microextraction (HS-SPME) combined with gas chromatography-ion trap
mass spectrometry for the vinyl chloride analysis in liquid and solid samples.
The Carboxen PDMS (Polydimethylsiloxane) 75 m fibre allows a limit of detection
of 50 ppt and 100 ppt as a limit of quantification in linearity and repeatability
conditions useful for control analysis. Moreover, the excellent affinity between
this fibre and the molecule of interest makes the use of little volumes of samples
possible. Each parameter had been optimized to obtain the best sensibility.
This method has also been applied to materials.
Key words: Solid-Phase Microextraction -- SPME -- water analysis -- vinyl chloride -- PVC.
