batch process to search old GC-MS runs for acertain compound

[dhdh]

I found several interesting compounds in some GC-MS runs. Is there a way (automated batch processing) to look through several years worth of GC-MS data files to see if that compound (or spectra) was present in the previous samples? The retention time wouldn't be the same over the years, but the MS ions and ratios should be similar. I have Agilent Chemstation & AMDIS software.

Hi dhdh,

I posted something about doing this in the following link

Search for a spectrum in another 100-500 gc-ms runs.

I just realised that was back in 2007 , time flies

Apologies for a slight thread hijack --

Chemstation, your other post that you linked to makes me think that you are something of an expert with AMDIS. Would you mind if I picked your brains ?

Hi Peter,

I wouldn't claim any expertise, just experience.

Alright! Thanks Alex. I dabbled in AMDIS when it first came out, but didn't get very far. If I get this to work, it should keep me busy (even after retirement when I no longer have access to an instrument). Thanks for the detailed step-by-step instructions. Excellent! Dan H

p.s. Speaking of "how time flies", would you (or anyone) know where I can get someone to transfer 1988-era GC-MS data files from the old HP tapes to CD or DVD?

Hello Dan,
Happy to be of assistance for AMDIS,

For the tapes, a search of the forum came up with a thread
Where to turn? Bringing a 5890/5970 GC/MS back on line
viewtopic.php?f=3&t=12548
that was written in 2010, in which the author describes
tape drive issues and repairs. He may know.

I'm guessing you have had this problem for a while

Thanks Alex, glad you're here! Yes, sigh, every so often I check for solutions (to my 2nd question). They stopped making the tape drives (and anything compatible) at least 20 years ago. My last hope now is to find someone with a working system (tape drive plus the PC with HP-IB card and cables) who will do it for hire. Dan
