All extraction salts, sorbents, and sample tubes are includedno specialized equipment or glassware is required. Prepare samples more efficiently with a complete line of QuEChERS supplies from Restek.
Multiple sorbents are used to extract different types of interferences.
MgSO4removes excess water.
PSA (primary and secondary amine)removes sugars, fatty acids, organic acids, and anthocyanine pigments.
C18-EC (end-capped)removes nonpolar interferences.
GCB (graphitized carbon black)removes pigments, sterols, and nonpolar interferences.
Note: No entry in the Method column refers to dSPE formulations not specifically included in one of the cited references. These products can be used to accommodate the various needs of specific matrices not directly met by the cited references.
