The Fredy & Nadine Herrmann Institute of Earth Sciences
Laser Ablation ICP-MS (LA-ICP-MS) Laboratory
The Hebrew University, Jerusalem
The laboratory operates an Analytik Jena Plasma Quant MS Elite quadrupole ICP-MS and ASI (SE) Resolution 193 nm excimer Laser Ablation systems covering a wide range of specific applications, the high-energy UV laser ablation (LA) system produces craters in the sample ranging in size from 2 microns to 100 microns. The ablated material then swept from the sample cell directly into the plasma of the ICP-MS. The ablated material then ionized similarly to any liquid sample aerosol. . The LA system is fully computer controlled with a real-time video imaging system capable of reflected and transmitted light (polarized light available) viewing. The system can programmed to ablate continuous lines, spots or a variety of more complex ablation patterns.
The Laser Ablation (LA) ICP-MS facility perform direct analyses of virtually any material. The LA-ICP-MS technique is particularly useful for in-situ analyses of trace elements for applications requiring understanding of the spatial variation of elemental content within the sample. The technique is capable of determining many trace elements down to low ppb and even ppt levels, although absolute detection levels are highly element, sample matrix and spot size dependent.
The LA-ICP-MS lab has been involved in a wide variety of studies involving geological, biological, environmental and material science related samples.
Current Analytical capabilities of the lab:
- Trace element analysis in various samples such as geological, biological archeological and Industries.
- U-Th-Pb isotope analysis of zircon and rutile.
- Powders analysis.
- Metal analysis.
- Air filter analysis.
- Food Industries analysis.
