TERMITE is an R (R Core Team, 2016) script for the reduction of LA-ICPMS data, which can reduce both spot and line scan measurements (Mischel et al., 2017). TERMITE is particularly useful for samples that are homogeneous with respect to their major element composition (in particular for the element used as an internal standard) and when many measurements are performed using the same analytical parameters. In this case, data evaluation using TERMITE is much faster than with all other available software, and the concentrations of more than 100 single spot measurements can be calculated in less than a minute.
Installation of R
Prior to the application of TERMITE, you need to download and install R on your computer. In case of any problems during the installation, please use the extensive documentation provided on the official website.
Application of TERMITE
- Download and unzip the TERMITE files. These are also provided at github.
- The file “step_by_step_instructions_TERMITE.pdf” provides detailed instructions how to run the script.
- The folder “your_main_directory” contains the R code of TERMITE as well as all mandatory files required to run the script. It also contains example data sets of a line scan and spot measurements.
- For spot analyses, the file “TERMITE_spotscan.r” is used. For line scan analyses, the file “TERMITE_linescan.r” is used.
In case of any problems or questions, please contact us.
