QuEChERS
QuEChERS (pronounced Catchers), is an acronym for Quick, Easy, Cheap, Effective, Rugged and Safe. The process is a sample extraction and clean-up technique widely used for the analysis of multiple residues in food, forensic and environmental samples.
Type of samples being analyzed:
Food Analysis
• Fish and Meat
• Fruits and Vegetables
• Grains, Nuts and Seeds
• Coffee and Tea
• Wine
• Nutritional Supplements / Botanicals
• Baby Food / Formula
• Oils
• Muscle and Tissue
Forensic Analysis

QuEChERS Method
The QuEChERS Method involves the following steps:
1. Acetonitrile salting-out extraction of a sample in an aqueous environment
2. Liquid-solid extraction - dispersive Solid Phase Extraction (d-SPE) - this removes the majority of the remaining matrix interferences
3. Analysis by tandem technique like LC/MS/MS, GC/MS or GC/MS/MS
