James, Thanks again. Actually, at first we had "EPC or detector error” and we tried to clean the detector but with no change. Once the GC says “Ignite, ignite” the error pops out. We tried second module (the refurbished) and at first we were receiving…
What are the pros and cons of putting a TCD in series with an MS? I know that it's possible to put a TCD and FID in series but I want MS data, not FID data. I tried teeing off the column between the MS and TCD but all the samples keep going to the MS…
ISH, that is a very good question. Yes, you can. However, you have to be mindful of a few things. For the Deans Switch to operate optimally, the downstream pressure need to be the same on both columns downstream of the Deans switch. The MSD operates under…
Dear Team,
Is it OK to use 8860 system for USP467, residual solvents analysis ? Literature that is available is mainly on 8890 but 8860 can also be used ? Agilent do have a blood alcohol analysis app note on 8860 with HS, 1 SSL, a Tee connection, 2…
In our company we are using a GC-FID Agilent technologies 7820A connected to a Headspace 7697A from Agilent also,
and we are not able to transfer some methods into our system when the carrier gas is Nitrogen.
Our team is in charge of the Method transfers…
We currently use Agilent 7890A GC with S/SL injector and FID detector using a capillary column for the analysis of crude oil composition upto C35. The remaining compounds will be reported as C36+. The temperature program is from 30 Deg to 325 Deg, We…
Hello Nur5ik
Thank you for your question.
Disconnect or loosen the sample probe and rerun the "restriction and pressure decay test".
If you pass the first step, sample prove might be plugged. You need to change sample probe.
If the same step…
Hi Everyone,
Please can you help me. We have been having repeatability problems on the HP7890B for a long time and can't get to the bottom of it. Analysing for VOC. I have run lots of RSD measurements (10 injections). A common thing we are seeing…
Hello all I'm looking at designing some standby methods for my 4 GC-FIDs and 3 GC-MSs as they are often sitting idle for 3/4 days a week and are happily consuming helium, hydrogen and generally sucking money away basically for no reason. Turning them…
Hi, exactly what you said and like what Lance Nelson pointed out,the septum purge flow cannot set on GC 6890 but we can control the septum flow by reduce split vent value or split ratio ,so you can reduce split vent value in method 1 from 197.1 mL/min…
