The metals department at Sierra is certified to conduct
trace metal analysis for water, wastewater, soil, and hazardous waste.
Sample preparation and analysis are performed using the most up to date
methods provided by the United States Environmental Protection Agency (US
EPA) and the State of California Department of Health Services (Cal DHS).
The department capabilities include, but are not limited to the requirements
found in Title 22 of the California Code of Regulations (CCR), the Priority
Pollutant list metals, analysis of Industrial Discharge for both the NPDES
and specific POTW permitting systems, and the 503 Rule required for treatment
plants.
Sierra Laboratories metals department has the ability
to offer its clients not only speed and efficiency in providing results,
but also reliable data and low detection limits. This is made possible
by the instrumentation Sierra has invested in, a clean and spacious working
environment, and experienced personnel.
The instrumentation used in the Metals Department is all
manufactured by the Perkin-Elmer Corporation. This includes the recent
addition of an Elan 6000 ICP-MS. The Elan 6000 is utilized for sub-ppb
detection limits in difficult matrices such as seawater and fish tissue.
The low detection limits are achieved using the ICP-MS in conjunction with
hydride generation or a separation column.
