Analysis of Pesticide Residues in Pistachios Using QuEChERS Extraction and Cleanup with Supel™ QuE Z-Sep+
Pistachios contain approximately 45% fat, which can result in a significant amount of coextracted matrix in the acetonitrile extract generated using the QuEChERS procedure. A zirconia based adsorbent significantly reduces coextracted matrix prior to LC-MS or GC-MS.
Analysis of Pesticide Residues in Cannabis Using QuEChERS Extraction and Cleanup Followed by GC/MS/MS Analysis
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.

Lysing Enzymes
Enzymes provide a non-mechanical method for cell lysis and protoplast preparation. It may seem like a simple process to throw in your enzyme, stick your tube in the water-bath and walk away, but what is actually going on in that
Analysis of Pesticides in Turmeric Powder by LC/MS/MS and GC/MS/MS after Cleanup with Dual-Layer SPE Cartridge
Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
Determination of N-Nitrosamines in Valsartan
Nitrosamines have been discovered as a serious contaminant group in active pharmaceutical ingredients (API) belonging to the sartan family. This article describes a GC-MS method for the determination of nitrosamines in Valsartan tablets according to US FDA guide lines that
Improved Recoveries and Lower Background for GC/MS/MS and LC/MS/MS Analysis of Pesticides in Green Tea
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.
