pXRF correctionCorrection and QA/QC - as simple as uploading the raw data.
pXRF machines drift. Is your data corrected?
How it works
Upload your certified standard values
Upload files from the pXRF machine, including sample IDs
Download corrected data and QA/QC reporting
- Standards analysed together with the samples are used to calculate the correction factors
- The algorithms used are given in these papers:
- Use linear or reduced-major-axis regression
- Complete control over the standards and calculation configuration used for each element
- Configure the correction acceptance criteria, e.g. 0.9 > m > 1.1 and R2 > 0.8.
- Organize data from different machines or locations into Projects
