A Multi-Residue Method Choice-QuEChERS

Originally designed to analyze fruits and vegetables, QuEChERS now includes a variety of products. Since being developed and released by scientists at the United States department of agriculture in 2003, QuEChERS has gained increasing popularity as a method of selection. It combines several sample preparation steps and extends the range of analytes recovered by older boring extraction methods. The growth of QuEChERS benefits from the emerging requirements for the determination of trace analytes in high-throughput environments.
The matrix includes:
• animal products – meat, fish, kidneys, chicken, milk, honey
• grains and cereal products
• food – wine, fruit juices, fruits and vegetables

The extension of the QuEChERS method not only demonstrates its function in sample extraction and purification, but also addresses concerns about detecting large quantities of pesticides, herbicides, fungicides, antibiotics, and other compounds throughout the food supply.
The basic form of QuEChERS consists of three steps:
1. Liquid microextraction
2. Solid-phase cleaning
3. LC/MS/MS or GC /MS analysis

QuEChERS continued to improve the sample preparation of analytes in various samples. QuEChERS has now become a generic technology, with many modifications, each variant designed to do one thing: rapid sample extraction and clean up.
These modifications include:
• increase the flux of samples while reducing the cost
• minimize degradation of susceptible compounds, such as base and acid-unstable pesticides
• extend the range of matrices applicable to this approach
