HPLC-ICP atomic emission spectrometry in environmental analysis
- GE Corporate Research and Development, New York, NY (United States)
Trace concentrations of many compounds are difficult to determine directly by traditional chromatographic techniques. Organosilicon compounds, for example, have no chromophoric groups. Size exclusion (SEC) and high performance liquid chromatography (HPLC) can separate high and low molecular weight organosilicon compounds, but routinely employ detectors with insufficient sensitivity for trace concentrations in environmental samples. Elemental analysis methods such as inductively coupled plasma optical emission spectrometry (ICP) provide excellent element sensitivity but no speciation information. Interfacing of a chromatographic method with ICP has been shown to provide quantitative determination of trace compounds while retaining the chemical speciation information. This work will describe the power of the HPLC-ICP combination for trace compounds in environmental samples to identify and determine ppm levels of organometallics.
