ARVADA, CO--(BUSINESS WIRE)--Dec. 14, 2007--Adding to the arsenal of LC instrumentation used in our cleaning validation business, PRA recently purchased a new Waters Acquity UPLC system. Waters Corporation has long been the "gold standard" in pharmaceutical LC analysis, and the Acquity system takes it to new heights with increased speed and far-better sensitivity and resolution than conventional HPLC. At PRA we recognized that pharmaceutical LC analysis (including cleaning validation) will eventually be dominated by UPLC instrumentation and replace conventional HPLC analysis entirely. As our customers introduce these UPLC systems in their laboratories for cleaning validation applications, PRA is ready to support them through their most difficult challenges.
