Frequently Asked Questions

Find Quick Answers

What file formats does the XRF Analyzer support?

The tool supports CSV and TXT files with two columns: energy (in keV) and intensity (counts). The first row can be headers.

How accurate is the element detection?

Detection accuracy depends on spectrum quality. The tool uses a database of XRF emission lines with typical accuracy of ±0.1 keV for peak matching.

Can I analyze multiple elements simultaneously?

Yes, the tool can detect and quantify multiple elements in a single spectrum, with results showing percentages for each detected element.

Is my data secure when using this tool?

All processing happens securely on our servers. Uploaded files are temporarily stored for analysis and automatically deleted after processing.
