Hi Carmen,
Visually check your column in signs of contamination of stationary phase. It looks like your column was too old. In that case you could just reverse the column direction, and put for for long term conditioning at room temperature, then condition…
What should you consider when selecting gases for your new GC or GC/MS system?
Which gases will you be using?
Did you c onfirm that gases available are a supported configuration for installation ?
Gas requirements are specified in Site Preparation…
Hello, I am running residual solvent testing on a product for my company and I am having issues with peak sensitivity. I am running this testing on a 7890/7697 GCHS-FID combo. I am tasked with coming up with a solution to this issue by only adjusting…
Hi Paul, thank you for your reply. I can't attach a full autotune report due to it failing mid run. I can however add the text file it generated.

I have proposed system from agilent 7890B to check high purity gases . system consists of TCD , PDHID and FID . me question is do you think that system is complicated and i have risk that if any fault happened the whole system will be down . How to guard…
Hello! My multisampler (G7167B: DEBAR00250) has the following error: compressor has error EE 30756,0. According to the manual, this indicates a possible hardware error. I ran a sample cooler function test, which failed, and the result comment is: target…
Dear colleagues
We have Agilent LCMSD 1260 Infenity /6130Quaderpole. we encountered this error: Install module C:\Chem32\CORE\HPSCIL00.DLL, failed
We want to know the cause and the solution for this error ?
Thanks in advance.
With my best regards…
We are running long term tests with multiple GC analysis, automatically controlled from LabVIEW via ActiveX communication with OpenLab EZChrom. We recently had an event in the EZChrom software creating problems; suddenly midway through the tests, the…
Dear Community
I am using a GC/FID from Agilent with Openlab CDS. The GC/FID has to columns (front and back) which gives a slightly different retention time for the same substance. I use both lines, one for the measurement and the other for the control…
I don't think it would have a problem as long as you're not trying to connect with both software platforms at the same time. I've seen other customers do similar things (GCMS/FID, using MSD Chemstation for MSD work and GC Chemstation for FID work).
