Emerging Chemicals of Concern for the Environment by SPE coupled with HPLC and HPLC/MS/MS Detection

Emerging Chemicals of Concern for the Environment by SPE coupled with HPLC and HPLC/MS/MS DetectionThe USGS has identified 95 organic wastewater contaminants (OWC’s) of concern (Kolpin et al. 2002). In this study, 80 percent of streams sampled contained measurable levels of OWC’s. This list consists of many new classes of organic compounds not amenable to the more common EPA GC and GC/MS standard analytical methods. These new classes of compounds include veterinary and human antibiotics, human drugs, industrial and household hazardous wastewater and multiple classes of hormones, which are generally larger and less volatile than analytes found on current EPA method lists. Reversed phase HPLC analysis with a polar mobile phase is particularly suitable to analyzing large molecules that exhibit low volatility. HPLC methods have been developed by Columbia Analytical Services in Kelso for the analysis of a wide range of these compounds utilizing UV and fluorescence detectors. Methods already developed include a number of estrogens and caffeine and its metabolites.
