SPCal

SPCal in an spICP-MS calculator with an interactive GUI.

Both quadrupole and ToF data is supported, with native import from Nu Instruments and TOFWERK ICPs.

Processing

SPCal has basic data processing and export functions including:

• histograms and distribution fitting
• particle composition by heirachical clustering
• scatter plots and PCAs
• particle filtering by signal / mass / size

Installation

Windows executables are available for each release.

To install via pip first clone the repository then install as a local package.

git clone https://github.com/djdt/spcal
cd spcal
pip install -e .

The program can then be run from the command line. See the help for extended usage.
