Hi!

I run a lot of samples on GC-MS, and want to quantify one specific compound. Can I use OpenChrom to integrate the area of one peak with a specified RT, as a batch process for all my samples/chromatograms, and export the results in a single/collected file?

know nothing about OpenChrom, but with UniChrom you can do such way:

1. Import all your files File/Open
2. Collect all the documents in singe workbook Edit/Collect batch
3. Prepare a macros that processes required compound (add integration and quantitation to macro sequence). Check how it works at single layer (chromatogram)
4. Run a macro on a selected layers (exec macro button dropdown list).
5. Extract a peak attributes to Excel using the functions (PeakIndex and OneParam() from the Excel add-in which can be installed from Reports/xla/unichrom.xla).
As soon the add-in enabled - these functions allow live data extraction from opened documents.
5.1. Or use an example VBScript or JScript from Reports/* to extract your data.

data processing in UniChrom is free

Thanks for your answer, I will try it out!
