Abstract

[Environmental chemical analysis has two parts—sample preparation and analysis. Today’s instruments measure extractions of the chemical that existed in an environmental medium, such as soils, so the first challenge is to remove the target chemical (“analyte”) purely from the medium. This step often is complicated by the extraction of unwanted chemicals, causing interferences, or by difficulties in removing all the analyte from the medium. Sometimes, the analyte is actually a group of chemicals, such as polychlorinated biphenyls (PCBs), which offer additional challenges. Common analytical instruments include gas chromatographs, mass spectrometers, and atomic absorption or inductively coupled plasma spectrophotometers. Operating each requires skill with sample preparation and the instrument, along with a chemist’s interpretation of the electronic output.]
