The Clean Lab
The clean lab is part of a two room suite designed to minimize the potential for even trace amounts of contamination to samples that are being prepared for analysis in the adjacent ICP-MS lab. HEPA filters in the ceiling vents provide purified air to the facility. Air pressure within the rooms is set at a high positive pressure while the vestibule entry to the lab suite is set at a negative pressure, causing any incoming dust to be blown out as someone enters the lab. All gas tanks used for ICP-MS analysis are contained in a separate, external gas closet in order to eliminate the possibility of any contaminants being carried in on gas tanks or transport carts. Ultrapure water is provided by a Millipore Milli-Q Integral water purification system. This lab is also outfitted with two HEPA filter hoods and one perchloric hood used for dissolving rocks and preparing solutions for ICP analysis. |
