متن کاملSolid-phase micro-extraction (SPME) in the early detection of potentially active volatile compounds from organic wastes used for the management of soil-borne pathogens.
The complex molecular assemblages were analysed in the soil gas phase after applying pine forest wastes (PFW) or sugarbeet vinasses (SBV) for soil-borne crop pests' management. For this purpose, solid-phase micro-extraction (SPME) and gas chromatography (GC) were used coupled with mass spectrometry (MS). The organic wastes were applied either to Calcic Entisol or Haplic Arenosol moistened at fi...
متن کاملVolatile profiles of toxigenic and non-toxigenic Aspergillus flavus using SPME for solid phase extraction.
Toxigenic and atoxigenic strains of Aspergillus flavus were grown on potato dextrose agar (PDA) and wetted (23% moisture) sterile, cracked corn for 14 and 21 days, respectively. Volatile compounds produced by A. flavus, as well as those present in the PDA controls and sterile cracked maize, were collected using solid-phase micro-extraction (SPME) and identified by gas chromatography/mass spectr...

متن کاملExtraction and analysis of polycyclic aromatic hydrocarbons (PAHs) by solid phase micro-extraction/supercritical fluid chromatography (SPME/SFC)
Solid phase micro-extraction (SPME) is a clean and simple pre-concentration method. Previously used for trace analysis of volatil compounds, the use of SPME was extended to non volatil molecules with the development of an SPME /HPLC interface. This new interface allows the extraction and the analyses of high molecular weight compounds found in aqueous samples. Since supercritical fluid chromato...
