Maintaining an on-site analytical chemistry lab to monitor air and site water quality

摘要

In the 1990s an industrywide trend to outsource support services emerged. Among the casualties of this trend was the maintenance of full-fledged analytical laboratory services for in-house quality control of incoming chemicals and real-time analytical support for the root-cause analysis of process problems. The quality assurance of incoming chemicals, which had previously been subjected to total in-house inspection, migrated to outside vendors, while fabs confined themselves to performing internal spot-test analyses.
