Our lab just got a GC/MS-FID installed and we are using MSD Chemstation data analysis instead of mass hunter. However, is there a way to only integrate the GC-FID tic and not the tic used for mass spec? (I hope that makes since) Or is it set up to integrate…

From your description (instrument configuration fails), it sounds like you will need to remove and re-install MH Acquisition. You might try a repair of the software.

Thank you very much! I'll make sure to have those items correctly. Our instrument (5975C MSD) has been in idle condition for over an year but under vacuum up until recently I started it again. My real issue is autotune fail. The tune fail symptom is Ent…
I am having difficulty with lighting the FID on my 5890 GC. I took apart the detector and cleaned as best as I could. I removed the jet and cleaned it on a sonicating bath. However, I am still unable to thread a syringe cleaning wire through the jet.…
Hello Kang: Generally, and aging lamp would be the likely cause of this problem. The average life of the 8453 lamp is 1000 hours. Lamp performance and lifetime may also be affected by physical shock while the lamp is hot, igniting the lamp while it's…
Your second sample set did not start because there is a conflict that could not be resolved. Instrument failures can be separated into method or sequence.
If you select your (failing) instrument method and press "Setup", does the instrument start equilibrating…
I have a 7890 and 5977a which have been sitting for a few years as the result of a failed business venture, I did some successful spme analysis on it a year or so back but just tried some tests from the ALS and it fails. I'm an absolute novice with this…
Hello everyone!
I'm currently working on a new (for my company) method of quantifying acrolein by GC-FID. I have a big problem with the appropriate weight of the standard. According to the article, I should add the right amount of acrolein to the CS2…
Hi Carol_Ultivo , There is always a trade-off or balance to be struck between Scan speed, mass resolution and sensitivity in any quadrupole mass filter. So, if you decrease the resolution and keep scan speeds the same you will naturally get an increase…
