SPEX CertiPrep celebrates its 50th anniversary this year.  For the past half a century, SPEX CertiPrep has made spectroscopy our business by being the first to design many of the ICP or ICP-MS standards you use today.  We were the first to manufacture and sell AA, ICP and IC standards.  In response to newer instrumentation, we designed the precise Claritas brand of ICP-MS standards, like nothing else on the market today.  Recently, we launched our newest line of Contamination Control Products.  We continue to design innovative new products to meet your needs.
