Metals Laboratory

The CAS metals lab analyzes drinking and nonpotable water, soil, solid, organic and miscellaneous samples.  Analytical capabilities include over 20 metallic elements, such as mercury, lead, and arsenic.

Often, metal samples must first be prepared before analysis can begin. Preparation includes digesting "or heating" the samples in differing acid solutions for specified periods of time at 95° C in order to dissolve the metals.  Once dissolved, the metals are contained in solution where they can more easily be analyzed.

Samples are analyzed using three different technologies:

Data generated by these techniques must be interpreted, reviewed, and processed by the analyst using appropriate software and method. The data is then arranged into a detailed report for database entry and further reviews.
