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…
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…
I have observed that when a method is transferred to a new system, you need to save it in the new system before using it. If you just copy the method and use it, sometimes it fails. Just by saving it, it makes it work. I guess it saves some defaults from…
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…

it does not work,
I tried to install openlab v2.4 manually, the installation failed at the agilent platform in the install or upgrade content management part,
We have an LC-MS with an Agilent 1260 Infinity HPLC stack, with a G7167A multisampler. The multisampler has one drawer installed with 2x 54-vial plates. We have had some communication issues recently where the transport initialistation kept failing after…
Hi Lycrecia,
We checked the volume calibration section and we did the full range volume dispense, as described in the manual. However, we are not sure which value we should add to the actual volume in the volume calibration screen. Do we need to do…
Hello, Your question brings some additional questions for me. You mentioned that your rescans are failing eventhough the product is correct. Is your method robust enough. You should not see many fails in a batch if the instrument is properly operated…
What are the detector voltages? Select the Hardware button, or Hardware/Dashboard from Task manager, and click the Detector image. Select EM setting. What are the voltages for Discriminator, Analog HV, and Pulse HV?
Was the instrument off, for an extended…
