This facility is a Class 10,000 clean room for the purpose of trace element analyses. Sample preparation areas are protected by HEPA-filtered laminar flow systems, providing Class 100 conditions to minimize contamination when handling and preparing samples. Multiple high-performance analytical instruments for analysis of trace elements, trace element speciation, non-traditional stable isotope ratios and trace emerging contaminants. Instruments housed within the clean room include: an inductively-coupled plasma optical emission spectrometer (ICP-OES) and a quadrupole ICP mass spectrometer (Q-ICP-MS) for quantification of dissolved constituents; a high-resolution ICP-MS (HR-ICP-MS) for trace metal analyses; a multi-collector ICP-MS (MC-ICP-MS) for non-traditional stable isotope analysis; a high-performance liquid chromatography - liquid chromatography mass spectrometer (HPLC-LCMS) for perchlorate analysis; an ion chromatography system (IC) for metalloid speciation (arsenic and selenium); a total mercury analyzer; and a laser ablation system.
