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…
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,
Please mention the instrument you are trying to work with.
Please see the following for GC:

I looked around but failed to find anything useful. Is there somehow possible to export results/data from SureMass-deconvolution/ID in Unknowns Analysis for further processing and or statistical analysis (besides .CEF-format)?
After most MSD maintenance (filament change/switch, source cleaning, etc...) I seem to have an issue with the baseline dropping in series (offset pattern) for up to 2 weeks afterwards. I'm new to this machine, but I'm in the process of slowly changing…
