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…
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
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…
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…
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…
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…
