Popis

General description

Stenerson, K.; Ye, M.; Halpenny, M., New Analytical Tools for the Determination of Persistent Organic Pollutants (POPs) in Fatty Food and Beverage Matrices Using QuEChERS Extraction/Cleanup and Gas Chromatography (GC) Analysis. Pittcon 2013. Sigma-Aldrich/Supelco publication T413034

Application

Extraction solvent: acetonitrile, 25 mL
Clean-up volume: 3 mL
Clearn-up tube: Supel^™ QuE Z-Sep (500 mg, part no. 55299-U, magnesium sulfate (450 mg, part no. 63135)

Analysis Note

Sample pretreatment: Place 5 g ground sample into 50 mL centrifuge tube. Spike with 100 ng/g target PAHs and internal standards. Let sit 30 min. Add 5 mL water and homogenize.

This application demonstrates the use of dispersive SPE or QuEChERS for the extraction and cleanup of raw salmon for GC-MS analysis of polynuclear aromatic hydrocarbons (PAHs). Supel^™ QuE Z-Sep sorbent was used in the cleanup step and found to reduce background and yield recoveries >80% for a majority of the PAHs tested.
