Update: FID output signal was very low even when trying to ignite, so we checked the interconnect spring and noticed it was shorter than the ones in the other GCs (not that close to the detector base; dont know if it was always like that or something…
Realize this was a while ago but I just came across it; wrote something similar a while back that processes the data in a given sequence folder - could easily be adapted to run as post-run and post-sequence or also with a specified folder. Hopefully this…
Thank you Paul! I haven't got a chance to try it yet. But I found the sample might carry too much salt (in heptane) that may damage the column and system. The drop always occurs right after one of the std peak which lead me to think it is somehow LRI…
