Dear team,
I'm running 8890 GC-FID using back injector and front Detector FID. When, we uploaded sequence table, there's message appearing that sequence table rear injection isn't detected. Can anyone help to advise what to do with that?
Thanks…
My knowledge of GCs is extremely limited. Currently we analyze for n-pentane only. The program was already set-up when I started working here.
Yes, an FID is present

I have a chemist who uses GC/MS and has been experiencing issues with running samples and when he connects to the workstation with GC/MS via VNC Viewer it causes the samples to fail and throw errors such as, "Cannon open file D:\MassHunter\GCMS\1\simulate…
While removing a column from an Agilent mass spec 5977B the column broke off and I can't figure out how to remove it. I'm using MassHunter version 10.1.64.1 (12/15/2021) but not actually using the mass spec but only the FID on the back. If I start a sequence…
I have the flex metal G3188-27501 ferrules. when it comes to the Inlet, the ferrules fit alright and I can tighten them onto the column. When it comes to the FID port, the ferrule is too long and I can't screw in the column to the outlet. If I really…
hi all,
we have ICP-MS 7800 and getting error 1445. The content of the error is as follows:
"1445, Error: Plasma gas flow rate is too low." We can't ignite plasma.
Gas valves and gas line have been checked and there is no problem.
Does anyone…
Hello!
I am inquiring about a Turbo-V 3K-T High Vacuum Turbo Pump which unfortunately failed due to a bearing problem. I would like to receive information and advice on the following issues:
1. Is a repair kit available for the Turbo-V 3K-T pump?…
How do I convert the Peak Area (pA*s) measurements in a GC-FID lab report into mass/weight percent of components for analysed crude oil samples?
How do I characterise the n-paraffins and estimate the single carbon number (SCN) distribution from the…
I'm running a GC(7890A) / MS(5975C) with MassHunter Acquisition software. I automate much of my data analysis in Python by exporting the GC signal (FID) to .csv, and then exporting the MS signal using 'Export 3-D Data...' in MSD Productivity Chemstation…
Hi all :) For he experts here! I did my yearly maintenance (new gold seal, liner, column end cut to inlet and FID, new gas filters, ...). But since then, everytime there's a temperature change in the GC, the signal will show a sudden bump and then it…
