애플리케이션

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)

분석 메모

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.
