Does anymore have./know of a macro for Agilent Enhanced Data Analysis Software (MSD Chemstation G1701FA F.01.03.2357) that enables the integration of a file (FID and TIC using the ChemStation integrator) to be saved so when you re-open the data file you…
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…
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…
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…
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…
Hello, I am troubleshooting a leak in the primary pump head of an Agilent 1290 G4220A binary pump. I am visibly observing that when the pump is operating, mobile phase is leaking into the seal wash lines. Also, by looking at the detector signals, I can…
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…

Thanks for this.
To make sure I'm understanding this correctly does this mean that the instant pilot is acting as the terminating end of the bus and that the socket that the instant pilot is connected to is the one that is failing when no instant pilot…
