The HEPA-filtered class-100 trace metal free lab suite includes working benches, laminar flow/fume hoods, a balance room, a dedicated beaker cleaning room. Inside this clean lab suite, there is also a super-clean room whose incoming air is purified by an additional layer of charcoal filter to further eliminate trace element contaminants associated with organic bound particles. The super-clean room is dedicated to processing of contamination-prone and/or ultra-low level elements from samples (e.g., trace metals in seawater). The clean lab suite is shared by Zheng research group and Edwards research group.
