Understand how to use dispersive SPE and traditional SPE cartridges for preparation of fatty matrices for the analysis of persistent organic pollutants.
Overview
Sample preparation for extraction of persistent organic pollutants (POPs) for gas chromatography analysis can be challenging, especially in samples with high fat content. Extraction methods targeting non-polar compounds such as pesticides, PCBs, and PAHs tend to generate extracts that are highly contaminated with fatty matrix, causing several problems with the subsequent chromatographic analysis. Traditional clean-up techniques, such as gel permeation chromatography (GPC) and normal phase column chromatography can be very effective but are often expensive and time consuming.
In this webinar, we will present an alternative approach to the clean-up of matrices with significant fat content using a family of sorbents that effectively retain fatty components. Examples will include analysis of pesticides using QuEChERS methodology and the use of unique solid phase extraction (SPE) cartridges for analysis of PCBs and PAHs in fatty foods.
Who should attend
Analytical chemists, laboratory managers, academic researchers, and anyone interested in food analysis.
