摘要: Publisher Summary This chapter reviews work on the analysis of aqueous leachate samples collected from two major industrial and hazardous waste disposal sites in California—that is, Stringfellow Casmalia Resources. Liquid chromatography (LC)–particle beam (PB)–mass spectrometry (MS) was chosen as method analyzing leachates because LC is suitable for handling quite polar thermally labile compounds PBMS can generate standard 70 eV electron impact (EI) mass spectra. Because PB–MS counts gas-phase ionization, still need to be volatile. The spectra generated searched with a computer against huge collection known MS library. Thus, helpful tool compound identification. primary intent LC–PBMS study identify chemicals present leachates. were lyophilized processed. sample extracts chromatographed high-performance liquid (HPLC) reversed-phase, anion exchange, or multiphase columns. detectors used included ultraviolet (UV), PB–MS, inductively coupled plasma (ICP)-MS.
