Chromatography Forum

Does anybody know about a free software to analyze gas chromatograms from Chemstation software?.

Thanks a lot

AMDIS is Windows-only and can open GC-MS data, but isn't open-source and can't handle FID files. OpenChrom and Aston (disclaimer: I wrote Aston) are both cross-platform, open-source and have support for both Chemstation MS and FID files (although OpenChrom can open more versions of FID).

What do you mean by "analyze" though? You can do integration and look at spectra, etc in all of these programs, but none of them (although OpenChrom may be close?) have the same quantitation support or the export-to-Excel-style reporting capabilities as Chemstation yet.

Thanks very much for your answer¡

shfo,

What file format does OpenChrom take? Ascii text, Chemstation .D files, ....?

Best regards,

OpenChrom can open text files (CSVs), MS Chemstation *.D files, NetCDFs and most other MS formats. That's about all I know, but there are also a couple threads on ChromForum about OpenChrom where you could ask the developer questions.

And in the interest of completeness: AMDIS supports most of the same proprietary formats (including MS Chemstation *.D's), but doesn't support text or NetCDFs as far as I know. Aston takes Chemstation *.D's (including LC Chemstation MWD & DAD files), some Masshunter *.D files, CSV's, NetCDF, and some random Bruker and Thermo formats that I've had time to decompile (I haven't had time to make proper documentation, so there's not an official list on the website yet).
