Andy G. had the excellent suggestion to decrease draw speed and wait time, since we are working with methanol extract. So we halved the draw speed from 100ul/min to 50ul/min and increased the wait time from 2 to 3 seconds. For now, this seems to have…
Hi guys, when I tried to run my sequence in GC-FID, the workstation showed "front injectors not detected", and under my method, the configuration showed no injectors. However, the parameters I entered for injection could be found in the GC (7890A) operation…
Hi everyone
In my company recently we update the Openlab Ezchrom to CDS 2,5.
We have a GC 7820A and when we analyzed Residual dissolvents we have a trouble because between 3 to 5 minutes the detector (FID) get shutdown and this signal of shutdown…
Hi Abdul,
From the picture, it appears your FID flame was extinguished. You can put a metal wrench or a mirror at the top of the detector to see if the exhaust contains moisture from the combustion, but a flat baseline at zero output usually means the…
This instrument is used mostly for FID analyses and the second injector is not working. That's the primary reason why the column will be disconnected most of the time. Also to reduce contamination of the ECD, but it sounds like that isn't a huge concern…
Good Day.
I have an issue to my result in tcd. My Sample is TOGA using Fid and tcd. now the issue is the detection of H2, N2 and O2 are late. before 4.2 min. now its 6.2. the column is new.
Thank you for the reply, I will have a go at it tomorrow. So essentially I just need to change one of my internal standard compounds to a normal compound, and use that as a single point calibration? It just seemed logical that every internal standard…
We need to use air generator for 8 GCs with FID Detector. Each FID uses 350 mL/min air. So for 8 FID, 2.8L air will be sufficient? Is it ok to go for an air generator that supply 3L of air/min or we need to go for a higher option? Kindly advise
