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.
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.
Simplified LC-MS/MS Method for Glyphosate, AMPA, and Glufosinate in Oat-Based Cereals
A simplified LC-MS/MS method to determine glyphosate and related compounds using a Supel™ Carbon LC U/HPLC column for stability under higher pH conditions and sufficient retention for the polar analytes in the presence of methanol as an extraction solvent.

Microbiology Introduction
Introduction to Microbiology Theory. An initial aim of all microbiologists is the reproducible growth of their microbial cultures, no matter whether the microorganisms are of natural origin or have been genetically engineered by man.
Speed, Simplicity and Accuracy of Protein Binding Determination using BioSPME
Learn about Supel™ BioSPME C18 high-throughput devices to determine plasma protein binding and decrease the sample preparation time to less than an hour.
Cleaning Up Samples using 2-D Clean-Up Kit
2-D Clean-Up Kit from Cytiva is designed to prepare samples that would otherwise produce poor 2-D results.
Dopamine, Norepinephrine and Ephinephrine Synthesis
Dopamine-β-hydroxylase is located inside amine storage vesicles of norepinephrine neurons. Dopamine is actively transported from the cytoplasm into the vesicles. As the enzyme is a copper containing protein, its activity can be inhibited by copper chelating agents, such as diethyldithiocarbamate
Glycosyltransferases: Tools for Synthesis and Modification of Glycans
The presence of multiple functional groups and stereocenters in complex carbohydrates makes them challenging targets for the organic chemist.
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.
Sample Preparation in Ion Exchange Chromatography
This page clarifies sample preparation, buffer exchange and desalting, removal of lipoproteins, phenol red, and low molecular weight contaminants in Ion exchange chromatography.
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.
