Frequently Asked Questions

Find Quick Answers

What file formats does the NDIR Analyzer support?

The tool supports CSV, TXT, and JSON formats. CSV/TXT files should have two columns: wavelength (nm) and intensity (arbitrary units). JSON files should follow the same structure in a key-value format.

Which gases can the NDIR Analyzer detect?

The tool can analyze common NDIR-detectable gases including CO2, CH4, CO, N2O, and water vapor. You can configure custom gases by entering their specific absorption wavelengths and calibration coefficients.

How accurate are the concentration calculations?

Accuracy depends on your calibration data and instrument specifications. The tool uses standard Beer-Lambert law calculations with user-provided calibration coefficients. For best results, use coefficients calibrated for your specific instrument.

Can I save and export my analysis results?

Yes, you can download a comprehensive PDF report containing all analysis results, spectral plots, and concentration tables. You can also export the processed data as CSV for further analysis in other software.

Does the tool require an internet connection for analysis?

File upload and initial processing require an internet connection. However, once data is uploaded, most calculations are performed client-side for faster response times, with complex spectral analysis handled by the backend server.
