Many modern, high-tech industries depend on the use of highly pure reagents. Monitoring the impurities in these chemicals and products requires special approaches to many analyses. At WCAS we have applied new technologies such as ICPMS, GCMS, GC, HPLC, and IC to electronic grade reagents, high purity acids, semiconductor dopants, synthetic organic chemicals, pharmaceuticals and others. Using ICPMS, more than 60 elements can be determined in a single analysis, most down to sub-ppb concentrations.  For a quotation......
