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…
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…
good day!
tell my please..
I have the air generator and his out pressure consist 52 psi, and and air consumption is 1000 ml/min. the EPC module GC 7890b work in rang 55-80psi. I have 2 detector FID. Tell my - with this generatorom may be worked ?…
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:

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…
