The Microbiology and Inorganic Chemistry Branch

The Microbiology and Inorganic Chemistry Branch is comprised of the Bio/Chemistry and Metals analytical units. These units are responsible for the analysis of bacteriological samples, nutrients, metals and a variety of inorganic parameters through other "wet chemistry" techniques. A complete list of parameters, arranged per analytical unit and responsible personnel, is detailed below.
