Chiron loss hammers home critical contamination control
After discovering serratia marcescens bacterial contamination in what it claims was a "limited number of lots" of its Fluvirin flu vaccine late this summer, Chiron Corp. (www.chiron.com) quarantined the approximately 46 million doses manufactured at its Liverpool facility and began an investigation into the cause of the contamination.
Better chips need purer gases
Recent announcements from Pall Microelectronics, a part of Pall Corp. (East Hills, N.Y.; www.pall.com), and Mykrolis Corp. (Billerica, Mass.; www.mykrolis.com) may portend a time when gas filters and purifiers are the same device, and when cleanroom air itself is purified, as well as filtered, to control contamination.
