Sample Preparation and Clean-up

Thermo Fisher Scientific Inc., the world leader in serving science, has introduced its comprehensive range of Thermo Scientific HyperSep Dispersive SPE products, which contain sorbents for optimal extraction, clean-up and separation of analytes from complex matrices using the QuEChERS method. Developed to overcome the issues associated with multi-residue methods (MRM), the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) method minimises reagent consumption and eliminates the requirement for any automation or labour intensive processes. Therefore, this method has been readily accepted by pesticide and residue analysts and is rapidly emerging as the method of choice in food safety laboratories.

The HyperSepTM Dispersive SPE products are available in a range of sorbent material combinations, each used to remove different interferences from the starting sample. As a result, researchers are able to determine a wide range of pesticide compound types (polar, pH dependent), while obtaining high recovery levels and accurate results. Furthermore, extraction in acetonitrile makes the QuEChERS method suitable for both GC and LC procedures. HyperSep Dispersive SPE products are supplied pre-prepared to save valuable research time and reduce any variability in resulting data.
