To avail of the analysis time, you need to write a brief proposal, which will be evaluated by a committee of scientists. Upon successful evaluation, you will be offered possible time slots for the measurement, as well as an estimate of the measurement duration and costs. After a mutual agreement has been reached, a more concrete planning can commence. text/html 2017-11-15T14:30:39+02:00 http://nanosims.geo.uu.nl/nanosims-wiki/doku.php/nanosims:contact?rev=1510752639&do=diff Contact persons involved in daily operation of the facility Lubos Polerecky room: 1.04 (PP9) e-mail: L.Polerecky (at) uu.nl tel: +31 30 253 5409 Michiel Kienhuis room: 0.04 (GML) e-mail: M.V.M.Kienhuis (at) uu.nl tel: +31 6 3733 8646 skype: nanoSIMS_Utrecht Visiting address Department of Earth Sciences - Geochemistry Faculty of Geosciences Utrecht University Princetonlaan 8 3584 CB, Utrecht The Netherlands text/html 2017-11-15T14:24:36+02:00 http://nanosims.geo.uu.nl/nanosims-wiki/doku.php/nanosims:home?rev=1510752276&do=diff NanoSIMS 50L is one of the advanced instruments of the National facility for high-resolution in situ isotope and element analysis.

Although originally “NanoSIMS” was the name of an instrument that makes such an analysis possible (NanoSIMS 50 or 50L, produced by Cameca), it is now commonly used as a synonym for the technique itself.

It is distributed as a Matlab code, thus requires Matlab (proprietary software) installed on your system to run. For the users of the Utrecht NanoSIMS facility, Look@NanoSIMS is provided on a dedicated computer available in the NanoSIMS lab. In addition to our collaborators, we recommend it to everybody to analyse their NanoSIMS data. text/html 2022-09-06T09:07:43+02:00 http://nanosims.geo.uu.nl/nanosims-wiki/doku.php/nanosims:lans_extras?rev=1662448063&do=diff Since its first release in 2011, LANS has been enhanced in numerous ways with features that are useful in different kinds of situations depending on how you wish to look at nanoSIMS data. The overall approach to the analysis, however, did not change. Therefore it is recommended that you first look at the manual to get started with the first steps of data processing and analysis with LANS.
