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…
Hello,
we want to analyse a gas mixture (CO2, CO, propane, ethane and methane in hydrogen) with the HP 6890 Series GC System (G1540A). The gases are coming to the column via a six-way valve and after the column, there is a TCD and a FID detector. In…
Hello Agilent Community Our Zero Air / Nitrogen generator from Parker Balston broke down and it has been discontinued. The supplier does not offer replacement parts and they do not longer have a gas generator model with the combination Air/Nitrogen. Therefore…
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…
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 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!
I've got a SEQ type CC that should be calculated only once during the reprocessing and a peak or group type that uses the result of the SEQ one. Since this the SEQ type CC is calculated inj number * peak number times.... is it possible to avoid…
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…
Are these FID issues only with this instrument or with others in your lab as well. If this is only on this instrument it might have to do with the H2 or air EPCs. If it is on other systems as well, you might want to check your instrument air. I have seen…
