Determination of volatiles in beer using solid-phase microextraction in combination with gas chromatography/mass spektrometry
GC headspace technique solid phase microextraction volatile compounds
2014/7/10
Headspace solid phase microextraction and purge and trap analysis were used for the determination of volatiles in beer. These methods were compared with the analysis of unconcentrated gas phase and li...
Analysis of ochratoxin A in malt beverage samples using dispersive liquid–liquid microextraction coupled with liquid chromatography-fluorescence detection
mycotoxin beverage microextraction HPLC
2014/2/24
A simple and economic procedure based on dispersive liquid–liquid microextraction has been applied to extract and pre-concentrate trace levels of ochratoxin A (OTA) in malt beverage prior to analysis ...
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...
