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…
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 am using MassHunter Qualitative Analysis B.07.00 to analyze FID data. I have extracted the FID chromatograms, identified the peaks and annotated them. But nothing happens when I try to print reports. Can anyone help me figure out how to generate the…
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…
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…
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…
Thanks, Marty! I'm unfamiliar with intelligent reporter, but it looks like that's what I need. This would be for a single injection. I would need it to display as another line under the main results, with an obvious notation, like pass/fail or reportable…
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…
Hello, I have the new MassHunter. Well, my P/A factor has failed. :-( do I correct this? I don't understand how to correct it. I am supposed to select a measurement from the "Load Mass List from Method". and added it. Unfortunately, the Current Value…
