QuEChERS 150 mg MgSO4, 50 mg PSA, 30 mg C18, 30 mg Al-N, 2 mL Tube, 100/pk

The QuEChERS method stands for Quick, Easy, Cheap, Effective, Rugged and Safe. The QuEChERS method followed by d-SPE is an easy-to-follow sample preparation technique that is ideally used for running multi-residue analysis for pesticides, veterinary drugs, and mycotoxins in a variety of agricultural and food-based products.

Many of the fruits and vegetables, such as spinach, red sweet pepper, and carrots, have very high content of non-polar pigments such as the carotenoids or chlorophyll. It is essential to remove some of the matrix constituents and pigments, especially for gas chromatography setups to ensure the pigments don't accumulate in the injection port or foul the injection liner. The QuEChERS effectively remove some of the components, such as fatty acids and sugars; however, samples may require additional treatment if they have high levels of pigment.

This particular lab equipment is a 2-mL tube used for cleanup following the exact step in QuEChERS sample preparation. Each d-SPE tube contains PSA, C18, and Alumina neutral sorbents suitable for mycotoxins analysis. Specifically, this tube contains 50 mg MgSO4, 50 mg PSA, 30 mg C18, and 30 mg Al-N. QuEChERS (pronounced catchers) methods are used for multi-mycotoxin residue analyses in grains. This package contains 100 d-SPE tubes.
