QuEChERS Dispersive SPE methods offer a convenient and effective approach for extraction and clean-up of pesticide residues in food and other complex matrices. The robust procedure offers a number of compelling advantages: high recoveries, accurate results, high sample throughput, low solvent and glassware usage, reduced labor and bench space and lower reagent costs.
Thermo Scientific™ HyperSep™ Dispersive SPE Extraction Products are available in a range of pre-prepared sorbent combinations, each containing the proper sorbents for optimum extraction of analytes using QuEChERS methods.
HyperSep Dispersive SPE Extraction Products use magnesium sulfate to aid extraction, along with either sodium chloride, sodium citrate, or anhydrous sodium acetate for base-sensitive compounds (e.g., folpet or captan). They are supplied in a 50mL polypropylene centrifuge tube for convenient extractions.
The dispersive SPE products are pre-prepared and optimized for the method at hand, so you will:
The QuEChERS method is a two-step process: extraction followed by clean-up. There are four variations of the QuEChERS method currently in use:
