Thank you for your response. I really appreciate your help. I realized I didn't provide clear information about the experimental conditions. Here are the specific conditions:
Inlet temperature: 250°C
Column oven temperature: 150°C (isothermal) …
Dear All,
We are using NGA analyser as per GPA 2286 method using FID and TCD.
Could you please advice how to apply the bridging to correct the concentration from FID.
Hi again Raina,
as I already told you this cannot be done with just one column, especially with the CO2 concentration up to 20% and water included and the necessity to analyze H2. This is an application we normally build an analyzer for. You need at…
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…
Hello taub .
I think it's a corner case issue and you need a support visit from agilent authorized engineer so please request a service visit as its seems that the error is hidden and not straight forward as you mentioned that you changed alot of things…
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.
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
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…
