A triple quadrupole GC-QqQ-MS/MS method was optimized for multiresidue analysis of over 180 pesticides in blackcurrants. The samples were prepared by using a modified quick, easy, cheap, effective, rugged and safe (QuEChERS) analytical protocol. To reduce matrix co-extractives in the

An analytical method was developed for the determination of phenmedipham (PM) in agricultural products using reversed-phase high-performance liquid chromatography with UV detection. A sample was extracted with acetonitrile, and the acetonitrile layer was separated by salting-out. The acetonitrile phase was

A high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/ MS) method was established for the determination of fungicide anilinopyrimidine residues including pyrimethanil, mepanipyrim, and cyprodinil in foodstuffs with series solid phase extraction (SPE). The food sample was first extracted with ethyl

Halogenated anisoles (methyl-phenyl ethers) appear to be ubiquitous organic trace compounds in the environment. An analytical method is presented for analyzing the altogether 134 congeners of chloro-, bromo- and mixed bromochloro-anisoles on an isomer-specific basis in air. High volume sampling
Supel™ QuE Verde combines a novel carbon with zirconia coated silica (Z-Sep+) to provide an optimum balance between planar pesticide recovery and color removal.

Compared to conventional PSA/C18/GCB cleanup, cannabis extracts cleaned with the Supel QuE Verde mixture showed lower GC/MS background, and better recoveries for many pesticides.
A procedure for cleanup of green tea extracts provides low background and allowed for the analysis of more pesticides at lower levels than QuEChERS. Uses less solvents and no toluene.
