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…
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…
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 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 :) 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…
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…
Dear Colleagues, apologizing for frequently wondering but I first faced this problem. GC produces a signal without turning on the FID Detector!? Please look at the attached photo. After turning on the detector and then conditioning the column while the…
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?…
Recently, we connected the column (CP7429) to TCD and FID using a Y splitter. However, there is no signal response on both TCD and FID after manually injection of the calibration gas (containing H2, CO, CH4, C2H4, C2H6 in CO2). The carrier gas is Ar.…
Hello,
To calculate the RSD and Pass/Fail results, one can try the following:
In the reporting go to the edtor and open "table properties"
In my specific case, I want to calculate RSD for Area, so I choose the column A, pA*s and press "Column…
