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…
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…
Hello,
We just recently got a new tapestation 4150 in our lab, which we're trying to set up. As a part of the setup I rand the full system diagnostics to see if the system is working with the Tapestation Test Tape. Everything runs successfully and the…
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…
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…
Hello dexter91, I need to have the column configuration from your system in order to give you a proper answer: are you using only 1 column with a splitter at the end to split it to the MS and the FID or you have 2 columns configured, 1 for each detector…
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…
