Application of single-drop microextraction coupled with gas chromatography for the determination of multiclass pesticides in vegetables with nitrogen phosphorus and electron capture detection
Amvrazi, E. G.; Tsiropoulos, N. G. (2009)In the present work the single-drop microextraction (SDME) technique coupled with GC-NPD and GC-ECD was evaluated for the determination of multi-class pesticides in vegetables. The donor sample solution preparation was ... -
Chemometric study and optimization of extraction parameters in single-drop microextraction for the determination of multiclass pesticide residues in grapes and apples by gas chromatography mass spectrometry
Amvrazi, E. G.; Tsiropoulos, N. G. (2009)A simple and rapid single-drop microextraction method coupled with gas chromatography and mass spectrometry (SDME-GC/MS) for the determination of 20 pesticides with different physicochemical properties in grapes and apples ... -
Determination of diphenylamine in contaminated air of agricultural buildings using active sampling on solid sorbents
Gagoulia, A. G.; Amvrazi, E. G.; Tsiropoulos, N. G. (2012)This paper reports the results of a study carried out with solid sorbents in order to establish the optimum procedure for sampling and determination of diphenylamine (DPA), the most widely used post-harvest chemical in ... -
Determination of Pesticide Residues in Honey by Single-Drop Microextraction and Gas Chromatography
Tsiropoulos, N. G.; Amvrazi, E. G. (2011)A novel, simple, and rapid single-drop microextraction (SOME) procedure combined with GC has been developed, validated, and applied for the determination of multiclass pesticide residues in honey samples. The SDME was ... -
Headspace single-drop microextraction of common pesticide contaminants in honey-method development and comparison with other extraction methods
Amvrazi, E. G.; Martini, M. A.; Tsiropoulos, N. G. (2012)In the present study the main factors that may influence the headspace single-drop microextraction (HS-SDME) of common pesticide contaminants (diazinon, lindane, chlorpyrifos ethyl, p,p'-DDE, and endosulfan) that may occur ... -
Pesticide enrichment factors and matrix effects on the determination of multiclass pesticides in tomato samples by single-drop microextraction (SDME) coupled with gas chromatography and comparison study between SDME and acetone-partition extraction procedure
Amvrazi, E. G.; Papadi-Psyllou, A. T.; Tsiropoulos, N. G. (2010)In this study a single-drop microextraction (SDME) method was extended for the determination of multiclass pesticides (metribuzin, vinclozolin, fosthiazate, procymidone, fludioxonil, kresoxim-methyl, fenhexamid, iprodione, ...
