Hello,
Our 6545 QTOF has been idle for a few weeks. When I checked the computer today, I found that "communication failed" errors had started appearing a few days after the instrument was last put to Standby. I'm not sure what happened as I don't think…
My manager is wanting me to add pass/fail system suitability assessments to my reports/processing methods. In order to limit my validation work and minimize the number of report templates that I am maintaining, I am trying to keep the report adaptive…
Won't start without a "Mating Connector"
I use RS232 to control the pump. The mating connector is not present,
The manual says short pins 4 and 5 and pins 8 and 9 of the IO port.
This results in ramp-up and fail.
What is the correct wiring for…
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…
GC and GCMS Supplies Recommendations for POIS 2020.pdf
The only change we made was to install a DB-VRX column. It goes to the Agilent splitter mounted inside of the oven, then goes to the FID and MS. When I inject a sample, the FID and MS chromatogram peaks follow each other perfectly. After the injection…
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…
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 Michael,
It's kind of a yes and no answer. Technically, the wavelength calibration will have failed because the strontium wavelength was not found - so you will see this if you check the results. Practically this is unlikely to impact operation…
Please check your data files and make sure the solvent peak is completely excluded . I have found that some data files I cannot detect ANY analytes of interest in Optimizer, even though I can identify them in standalone Unknowns Analysis. Without fail…
This Information Applies To: Agilent G1312X and G7112X binary pumps.
Issue:
A blockage before the pressure sensor, e.g. in a pump head, will not give a high pressure or overpressure system error. Instead, the pump may show one of various error messages...
