Summary/Comments:
The basic requirements for a trace metal clean room are minimal. They include metal free work surfaces and hoods, positive pressure with HEPA-filtered air, and clean (18.3 Megohm.cm) water; Each of those requirements may be readily achieved with commercially available materials, and they may be easily installed within existing facilities at relatively little expense. The document is divided within several sections describing the change room and the clean room required for such experiments. Concerning the Ultrapure Water, it needs to be plumbed into the clean laboratory. An outlet should be located near the work surface to minimize movement within the area during chemical processing. Movement may be minimized by locating systems near the entrance to the clean room or within the change room, and by plumbing the water to a carboy with a spigot near the back of the laboratory. This location of systems minimizes the potential for contaminating the work area with metal or paint flakes from the systems or while replacing cartridges within the system. It also minimizes the potential to contaminate the systems by maintaining them in a clean laboratory.
