AN409: Fast Determination of Acrylamide in Food Samples Using Accelerated Solvent extraction Followed by Ion Chromatography with UV or MS Detection

Instrument Type: IC

This fast determination of acrylamide method consists of a fast, automated extraction method, which finish extraction in 20 min using accelerated solvent extraction using pure water, water with 10 mM formic acid, or acetonitrile. The extracts were then directly analyzed by ion chromatography (IC) using a 4-mm ion-exclusion column and both UV and MS detection. Results were obtained for acrylamide in french fries, potato chips, and crisp bread.

Effective extraction of beta-agonists from pork using in-line SPE

Instrument Type: HPLC

In this example, pork was extracted with organic solvents in a Thermo Scientific ASE Accelerated Solvent Extractor. Evaporation and reconstitution were difficult, so it was overcame by using solid-phase extraction (SPE). SPE is most effective when it is orthogonal to the analytical separation, so a Thermo Scientific Acclaim Mixed-Mode WCX-1 cartridge was used to retain the drugs, and washed away lipids and other interferences with organic solvent. The auxiliary valve then transferred the drugs to an Acclaim C30 column for RP-HPLC analysis.
