Cameca IMS 1280-HR
The IMS 1280-HR is the latest ion microprobe manufactured by CAMECA. A wide range of elements (from H to Pb) can be obtained with an unequalled analytical performance, even for low contents (< 1ppm). The new design of the ion probe allows the precise determination of a large number of isotopic systems with an excellent precision, due to its capability to reach very high mass resolution (> 20 000). The lateral resolution is usually 10 µm, but could be as low as 2 µm. Depth resolution is in the order of hundreds of nm.
SwissSIMS is a national facility co-financed by the Swiss National Science Foundation for Research (SNF), and a consortium of scientists from the universities of Lausanne, Geneva, Bern and the ETH of Zurich. The ion probe was delivered late August 2012 and its installation ended early December 2012. After several months of development, scientific measurements have now started.
