SampliQ QuEChERS Extraction SPE Kits Information

 

Step One: Extraction
Adding solvent and salts to a small (10g or 15g) comminuted fruit or vegetable sample 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.

The Agilent Difference
Unlike other suppliers of QuEChERS extraction kits, Agilent SampliQ's salts and buffers are pre-packaged in anhydrous packages. This allows you to add them after adding your solvent to the sample, as specified in the QuEChERS methodologies.

Extraction Kits include: 50 quantity of 50 mL polypropylene centrifuge tubes with caps MgSO4 and NaCl, or other salts for buffering; pre-weighed in anhydrous packet (see chart below for specific components)

*Katerina Mastovaka and Steven J. Lehotay have done work to extend the scope of QuEChERS beyond fruits and vegetables(1), using it to extract acrylamides in potato chips and other fried foods. 1) "Rapid Sample Preparation Method for LC-MS/MS or GC-MS Analysis of Acrylamides in Various Food Matrices", J. Agric. Food Chem, 2006, 54, 7001-7008.
