Technology Opportunities

Objective/function

• The Clean Laboratory is used to prepare samples with pico- to nano-molar levels of trace metals for concentration and isotopic composition analyses

Research provided

• The Clean Laboratory is currently engaged in collaborative research on
• The effect of climate on rock weathering and soil formation processes
• Tracing the sources and geochemical characteristics of desert dust transported to Israel
• Characterization of trance-boundary air pollution using Pb isotopes and trace metal ratios
• The behavior and bio-availability assessment of toxic metals (Pb, Cd, Zn, Cr, and Cu) in contaminated soils
• Tracing end-member fluid sources and environmental conditions of sub-surface iron mineralization and dolomitization

Advantages

• The Clean Laboratory was designed with surfaces made of non-corrosive, acid-resistant, metal-free plastic materials, a monitored positive pressure air supply with HEPA filtration, and its own clean water supply

Client record

• The Clean Laboratory works collaboratively with researchers from Hebrew University, Weizmann Institute of Science, Ben Gurion University, Tel Aviv University, The Geological Survey of Israel, University of Michigan, Arizona State University and ETH, Switzerland

Available equipment

• Agilent 7500ce ICP-MS for trace metal analysis
• Nu Instruments Multi Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS) for isotopic analysis of Pb, Sr, Nd, Fe, Cu, and Zn (located at the Geological survey)
• Perkin Elemer Optima 3000 Inductively Coupled Plasma Spectrometer (ICP-OES) for major element analysis
• Perkin-Elmer PC-5100 ZL Graphite Zeeman-effect corrected furnace (HGA) for analyses of low concentrations of trace metals
• Perkin Elmer LS30 Luminescence Spectrometer
• Camspec single beam M330 UV/vis Spectrophotometer
