SOLID PHASE MICROEXTRACTION FOR TRACE ANALYSIS OF BENZENE IN ENVIRONMENTAL MONITORING
Headspace solid phase microextraction
2010/4/2
Conventional analytical method for organic pollutants in water requires extraction of the pollutants, using hazardous solvent. Solid phase microextraction is a solvent free equilibrium extraction meth...
Solid-phase microextraction for analysis of mould cheese aroma
SPME gas chromatography mould cheese aroma compounds
2014/3/17
Solid-phase microextraction coupled with gas chromatography was used for the analysis of volatile aroma compounds in Niva cheese. The extraction conditions were very mild, which minimises thermal, mec...
Determination of vinyl chloride monomer in food contact materials by solid phase microextraction coupled with gas chromatography/mass spectrometry
migration solid phase microextraction (SPME) vinyl chloride monomer
2014/3/19
The present study concerns the optimisation of the headspace solid phase microextraction (HS/SPME) combined with gas chromatography/mass spectrometry (GC/MS) for the vinyl chloride monomer determinati...
