Material Measurement Laboratory /Chemical Sciences Division

Inorganic Chemical Metrology Group

The Inorganic Chemical Metrology Group is responsible for developing, critically evaluating, and applying techniques for the identification and measurement of inorganic and organometallic species using X-ray, optical, and mass spectrometry as well as classical analytical methods, pH, and electroanalytical methods.

Standard Reference Materials (SRMs) and analytical methods development support a variety of industries including advanced materials, cements, ores, and fossil fuels, as well as clinical, food, and environmental analyses. The group develops and maintains primary national standards for elemental and anionic concentrations, pH, electrolytic conductivity, and isotopic abundance.
