Save time and achieve more accurate pesticide determinations using Thermo Scientific™ HyperSep™ Dispersive SPE Mylar Pouches. 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.
Convenient HyperSep Dispersive SPE Mylar Pouches each include 50 pouches of pre-prepared sorbent. Plug seal caps are not included.
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).
All HyperSep Dispersive SPE products are pre-prepared and optimized for the method at hand, so you will:
Developed by the USDA Eastern Regional Research Center in 2003, the QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) technique is increasingly becoming the technique of choice for extraction and clean-up of pesticide residues.
The QuEChERS method is a two-step process: extraction followed by clean-up. There are four variations of the QuEChERS method currently in use:
