Hello.
I'm hoping to seek some help for a problem I've been experiencing. We currently run a GC-FID with a headspace sampler testing for Acetic Acid, Propionic Acid, and Butyric Acid. I've been having issues reading the acetic acid consistently. Any…
I have configured my laptop to our 8890 GC with a split/splitless inlet and FID. I am currently just doing manual injection. When sending the method from my laptop to the instrument, all of the parameters reach the setpoints except for my column temperature…
When running hydrogen carrier your source should not need as much physical cleaning (compared to helium carrier) because the H2 has a scrubbing effect. So far I've been told that there is no physical cleaning on the HydroInert source as it could damage…
Hi everyone!
I have brand new PGC Yokogawa 8000 equipped CP-Chirasil-Dex CB Columns with FID detector and Liquid Sample Valve (LSV) set at 170C deg. The problem is GC can’t separate m-Xylene from p-Xylene in low concentrations.
Component name…
Hi everyone! Please help me to fix the problem. I have been using Agilent 6470A.
What could be the reason for the error on the pics? MS1 and MS2 «RFPA functionality Failed». It appears everytime when I’m doing QQQ Power On Diagnostic.
Hi Crystalnipp (great username!!) Thanks for the clear answer I do have a question for you. We also run N2 make-up to our FID. As of now we run He and our night standby method is to leave the GC oven at 150°C with 0.5mL/mim He flow. We turn flame and…
Hi All.
I've installed many time Openlab from version 2.0 to 2.5 but this is the first time I get this error on a new computer that IT gave us.
Trying to install Openlab 2.5 Workstation on Win10.
It fails at the "Openlab Chemstation Access" step…
Hi All,
For the last 1.5 years, the pump has been running fine even though the rear seal wash was blocked. Then in September, we were having issues with our pumps and found there was leaking in pump B. We did a maintenance, meaning cleaning the pumps…
Hi everyone,
We have detected fails in 3 FLD modules installed in the same instrument.
The fist of these gave the error 06712 (emission motor did not find position),and was replaced with a second module. This when it was being installed failed again…
Hi acraig First replace saptum until if you don't detected leak because sometime tiny leak in saptum cause low sensitivity. Second sometimes over tightening the ferrule connection of column to injector cause constriction the flow and reduce analyte at…
