A Comparison of Two Solid Phase Extraction Methods for the Analysis of Polyaromatic Hydrocarbons in Butter

This comparison shows that the Supelclean™ EZ-POP NP method produced better recoveries and lower background than direct SPE using a large silica cartridge for the analysis of PAHs from butter. When using EZ-POP NP, the final extract is clean enough for GC/MS analysis using the SLB®-35ms capillary column and single quadrupole instrument.
