Fortunately yes, so I am covered from that point of view The GC over here is a combo MS-FID machine which can be build to either MS of FID mode. It was in FID mode the last couple of days. Just rebuild the GC to MS mode, but I didnt perfom a full-on cleaning…
Hello,
I have a G6545 QTOF / 1260 HPLC system that came with an HP Z440 workstation with Windows 10 as part of the purchase from Agilent. The workstation is ~ 3 years old. The instrument was running normally over the weekend -- when I came back, the…
Hello,
I have been struggling with this coding error with OpenLabs Chemstation Report layout, I'm hoping the Agilent community may have a solution to my problem.
I'm told that the coding language for the Openlabs report templates is pretty much the…
I'm trying to develop a method for ethanol via headspace. I am using Restek standard Residual Solvents #1 (34105) for the curve. My instrument is Agilent 6890 GC-FID with CTC PAL COMBI autosampler for headspace.
I ran residual solvent curve at high…
Want to quantify or at least qualify trifluoroacetic acid (tfa) on our column, which is almost exclusively used for quantifying propionic acid, with acetic acid as the internal standard. Both dissolved in acetonitrile. It seems like tfa would work, but…
Thank you for your question. Unusual high low voltage error is a common instrument and accessory maintenance related and not instrument hardware related issue. Typically, when you see that error, under logbook of your run, you will see chip map. Please…
Hi dmarchini, I have attached a guide for some recommended spares. The questions of cost to maintain any GC is a difficult one as the application and sample amount plays a major role. Replacement of the consumables will vary because of this. The guard…
