About Instant Raman

I built this because I spent too much time as a research assistant doing the same repetitive tasks after every Raman session. Getting from raw instrument data to a figure that actually looks good in a paper took much longer than it should. I wanted something that just worked.

You can drop your spectra in and get your baseline corrected, peaks detected, and figures generated immediately. You get PNG and SVG files for your paper, an Excel file with the processed data, and an interactive report you can send to your supervisor. They can open it in any browser without needing special software.

What it handles

It reads files directly from Renishaw, Horiba, WITec, and Bruker instruments, or standard CSV and TXT files. It uses SNIP for baseline correction and finds peak centers with sub-pixel accuracy. If you have overlapping peaks, you can use the LM fitting tool with Lorentzian, Gaussian, or Voigt profiles. If you have multiple samples of the same thing, it can average them and show you the standard deviation.

The limits

This tool is honest about what it sees. If your peaks overlap too much for the simple detector to be accurate, it will show you a warning rather than giving you a number it isn't sure about. In those cases, you should use the fitting tool for a better result.

The basics

Instant Raman is free and runs entirely in your browser. Your data stays on your computer and never gets uploaded to a server.

If something isn't working for you or you need a feature that's missing, let me know. Feedback from people actually using this in the lab is how it gets better.
