Project Objectives

The USGS Mineral Resources Program and other USGS scientific mission area scientists need specialized routine analysis in order to carry out their research. This project facilitates the ability of the scientific staff to obtain these analyses. The Central Mineral and Environmental Resources Science Center (CMERSC) Analytical Chemistry project combines and coordinates the chemistry functions that are necessary for research and assessment projects within the USGS scientific mission areas. The project is responsible for: the physical preparation and tracking of the samples through in-house and contract laboratories using and automated sample control system; routinely analyzing samples using methods such as Instrumental Neutron Activation Analysis (INAA), Wavelength Dispersive X-Ray Fluorescence (WDXRF), atomic absorption spectroscopy, and instrument analysis; validating both in-house and contract analytical techniques, monitoring contract chemistry data quality and validating contract chemistry analytical results; disseminating analytical results to staff scientists; administering the Laboratory Information Management System (LIMS) which is fully integrated with in-house laboratories and sample control; and maintaining and growing the national geochemical sample archive. Recurring efforts include: maintaining equipment and methods of analysis for in-house analytical chemistry work; offering a mechanism to prepare samples; contracting routine chemical requests to an outside laboratory; and providing data quality control for both in-house and contract generated data. Long term efforts include continued support to the USGS by providing these services and the modification of these analytical methods or administrative procedures to better meet the needs of the scientists.
