It is used in biological assays to study the effects of manganese on the central nervous system, and to assess exposure limits.

Supplier: Thermo Fisher Scientific
Description: The QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) technique is increasingly becoming the technique of choice for the extraction of pesticide residues in fruit, vegetables and other foods. The QuEChERS method offers the advantage of high recoveries, accurate results and high sample throughput, combined with the associated cost savings with low solvent and labour requirements. Yet the procedure is robust and rugged.

Supplier: Agilent
Description: Step 1: Extraction
Choose the extraction salt packet based on your method of analysis, AOAC or EN. The buffered extraction salts are amenable for more liable pesticides. Adding solvent and then salts to a comminuted fruit or vegetable sample (10 g or 15 g) enables you to extract the pesticides of interest into the organic layer. However, adding a food sample with a high percentage of water directly to the salts may create an exothermic reaction that can affect your analyte recoveries.

Catalog Number: (HEWL5982-5258CH)
Supplier: Agilent
Description: Step 2: Dispersive SPE cleanup
Select the dispersive SPE kit suited to the type of food being analysed and the method you are following. In this step, an aliquot of the sample extract from step one (see QuEChERS extraction kits) is added to a 2 or 15 ml centrifuge tube containing a small amount of SPE sorbent and MgSO₄. The sorbent will pull out interfering matrix materials from the sample, while the MgSO₄ helps remove excess water and improve analyte partitioning.
