Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) was used to analyse microbial volatile organic compounds (MVOCs) of mushroom disease-related microorganisms.

Jan 02, 2006 · One possibility of silicone septa contamination relates to diffusion through the headspace, as characterized in Figure 3b and c, where the septum was punctured once by the 10-μL syringe needle with a 250-μL aliquot of hexane sealed in the vial. With the sensitivity of the method herein, no contamination was detected 8 hr after puncturing, and

THMs and MTBE are measured in drinking water by solid phase microextraction/gas chromatography/isotope dilution mass spectrometry (SPME/GC/isotope dilution MS) based on the method described by Cardinali, et al. (1). The analytes are in equilibrium between the drinking water and the headspace above the sample. A solid-phase
