Hi all, I am using a GC 6890 with split/splitless inlet to analyse reaction products. However, a problem has recently happened when the GC is running. I have noticed the appearance of spikes in the baseline of the FID detector. The spikes appear occasionally…
Hello, im having a problem with a 2d GC using the Deans Switch system. Its a 8890 GC with 2 FIDs. The problem is that, when cutting peaks from the 1st dimension to the 2nd dimension (2nd column), all peaks on the 2nd dimensions get split into 2 peaks…
Hello, Software used: - MassHunter Workstation Version 10.1.49 - MassHunter Qualitative Analysis Version 10.0 - MSD Chemstation Data Analysis (can't figure out version, when I click the help button error message "failed to launch help" appears) I am having…
External Device not ready. Is it an Agilent Autosampler? Which model? Do you have another device like a headspace sampler?
APG Remote. There is a cable between the GC and the MSD so that they both start at the same time. A remote start cable from another…
I am running on an Infinity 1260 II Ultivo LC/QQQ and have a problem when running check tunes. Every time I run a check tune, I get an out of tolerance result where the only parameter out of range is the gain factor. It fluctuates between being out of…
Hi all,
I am having a recurring issue throughtout my sequences. When I check the sequence log after a run, where I place a masscal between each sample, I see in the sequence log the following error:
5) MassCal: ' ' Starting QTOF MassCal: Mon Nov…
Hi, I have a agilent GC 7890B with FID. currently i am a facing a problem regarding this GC, problem is like that - all gases supply is ok, no leakage is found in detector portion. i have cleaned the FID & Jet but flame is not burning. So kindly suggest…
Hi all,
I'm using a 0.18 mm HP-5 GC Column on a Shimadzu GC-2014 connected with a FID. I'm looking to get new ferrules (the old ones had been passed down from previous users) and wanted to discuss some options. I tried using some 0.5 mm graphite ferrules…
