Abstract
The Viking SpectraTrak (Trademark) 672 GC/MS is an integrated system combining a temperature programmable gas chromatograph combined with a Hewlett Packard quadrupole mass spectromoter. This self-contained, field transportable system, whose design has been adapted from laboratory technology, uses a contained, chromatographic column and accompanying mass spectrometer to provide separation, identification, and quantification of volatile and semi-volatile organic compounds in sample matrices that include soil, liquid, and gas. The column enables the separation of individual analytes in complex mixtures. A mass spectrum, produced for each compound in the sample, can be used for compound identification and quantification. An integrated computer and data acquisition system enables identification and quantification of the analytes by comparison of detector response with a calibration table constructed from standards of known concentration. The system provides detection limits that range from about 5 ppm for direct gas injection to as low as 5 ppb for many volatile and semi-volatile organic contaminants in soils and liquids.
