The Region 9 Laboratory has a wide range of analytical chemistry capabilities to support environmental decision-making. In addition, the following determinations for soil are performed. Inorganic constituents in water, soil and animal tissue are determined by a variety of techniques at the Region 9 Laboratory. After applying one of several digestion techniques to a sample, the digested sample is introduced into the ICP which is capable of measuring up to 24 inorganic elements simultaneously. After applying one of several digestion techniques to a sample, the digested sample is introduced into the GFAA system which measures a single element at a time.
Concentrations are usually in the sub ppb range.
Detection limits are typically well below the ppb level. Colorimetry - After proper preparation of environmental samples, cyanide and hexavalent chromium are determined by colorimetric techniques. The Region 9 Laboratory uses several gas chromatographs equipped with different selective detectors to measure a variety of organic chemical constituents in environmental samples. The Region 9 Laboratory is committed to keeping up with the evolving needs of our clients. In this regard, the following projects are currently under development.
