Simultaneous determination of procymidone, pyridaben and beta-cypermethrin residues in tea solution by GC-ECD.
A sensitive and effective method for the simultaneous quantitative determination of procymidone, pyridaben and beta-cypermethrin residues in tea solutions was developed and validated using a gas chromatograph (GC) equipped with an electron capture detector (ECD). The analysis of the three pesticides in tea solutions involved extraction with petroleum ether-ethyl acetate (3:1, v/v), cleanup usin...
متن کاملAn Improved GC Method for Rapid Analysis of Valproic Acid in Human Plasma Without Derivatization
A simple, reproducible and rapid gas chromatographic method for precise determination of valproic acid (VPA) in human plasma has been developed. Total time for sample preparation and GC analysis is less than 45 min. After plasma protein precipitation, VPA was extracted into chloroform with suitable recovery. By using Stabilwax®<span styl...

متن کاملMultiresidue method for determination of 20 organochlorine pesticide residues in fruits and vegetables using modified QuEChERS and GC-ECD/GC-MSD
A rapid multiresidue method has been developed for the analysis of 20 organochlorine pesticides (OCs) in fruits and vegetables. The method is based on a modified QuEChERS procedure employing acetonitrile for extraction and partition. Dispersive solid-phase extraction (dSPE), containing primary and secondary amine (PSA) and graphitized carbon black (GCB), was used for cleans-up. Analytical deter...
