Inductively Coupled Plasma - Mass Spectrometry (ICP- MS) allows the quantification of trace and ultra-trace elements (mg/kg to pg/kg) by separating elements as a function of their mass-to-charge ratios (m/z) after ionisation into an argon plasma. Nevertheless, the provided "Results" module is uneasy to use and the generated raw data are very long to treat using an "homemade" spreadsheet.
So as to provide a free, easy-to-use and fast data treatment software to the ICP-MS users community, authors have developed uFREASI.
The processing is the step-by-step procedure used by uFREASI to calculate concentration from raw intensities. Processing steps are represented by rounded rectangles and decisions by diamonds.
This procedure increases the quickness of data treatment and improves its reliability. Also, in order to control the validity of the external calibration, the stability and the cleanliness of the device after analysis, uFREASI gives automatically the possibility to monitor important analytical parameters.
The following tutorial shows an example of the treatment and the monitoring by uFREASI:
uFREASI is made for ICP-MS users. This software:
uFREASI is freely downloadable (LGPLv3 license) on this website for different operating systems:
