This application note outlines a viable method for reliably detecting low-fem- togram levels of perfluorinated carboxylates (PFCA) and sulphonates (PFSA) without background component interference, with an inline contaminant trap LC modification. Good chromatographic resolution of all perfluorinated compounds was observed. A representative suite of PFCAs and PFSAs were analyzed herein and were all detected at on-column levels lower than 75 fg in drinking water matrices (S/N >3.) The most sensitive analytes PFHxS, PFDS and PFBS were detected at 2.6, 3.2 and 5 fg levels, respectively. Method detection limits for spiked pork liver matrix extract samples were below 600 fg on-column for the entire analyte suite. No detectable background conta- mination was observed in blank injections for any analyte in this study. Linearity for up to five orders of magnitude with R2 values above 0.996 for the entire suite were recorded.

The Agilent 7700s ICP-MS is a high-performance mass spectrometer designed for semiconductor applications, offering unmatched sensitivity, matrix tolerance, interference removal, and stability.

This article describes the determination of aflatoxins using Agilent 1290 Infinity LC, Agilent 1260 Infinity Binary LC, and Agilent ZORBAX RRHT 1.8 µm columns by fluorescence detection after electrochemical derivatization. The use of shorter columns instead of conventional 5 µm columns accelerates the HPLC and post-column derivatization method for the determination of aflatoxins B1, B2, G1, and G2. Despite the use of the Coring Cell and related band broadening techniques, high resolution was achieved. The analysis time was approximately 10 minutes, including column flushing, and the sample throughput was increased by more than 2 times.
