User could not tune and was getting missing .xml errors. This error was observed in MassHunter Acquisition software B.07.00 on a GC QQQ but may be relevant in other revisions as well. Error in auto tuning! Missing XML file or invalid contents. Failed…
Slightly related: As part of a new lab setup, I decided I could greatly save having to replace cylinders if I ran my FID on a one-fifth flow of pure oxygen instead of compressed air.... Maybe you could guess the result. Every ignition was a detonation…
Your controller is going in Auto Tune
Autotuning condition is shown when the controller has delivered an output power level higher than a typical value, but the pump is still not reaching full speed value.
It does not matter if it is a normal start…
Hello! I followed this tutorial part D Linked Dual GC Signals 1 aliquot /cfs-file/__key/communityserver-discussions-components-files/152/0020.DualTow7890EnvMH.pdf to sample 1 aliquot through both the front and back autosamplers, both columns, to both…
I got a data sheet for my Agilent 7890 FID detector. The stated linear range is 10x7. This range I think should mean that from 1% down to 0.1 ppM the detector is linear for Tridecane. I figure concentration-wise in splitless mode - that works out to be…
Hello, We are using Agilent 7890B GC/FID with Headspace sampler. There is a problem in FID unit of the system. In FID parameters, Temp is 220 C, H2 fuel flow is 30 mL/min, Makeup flow (N2) is 25 mL/min, He flow 1 mL/min. These are setpoints and actuals…
It is a capillary, USP 401 The gas chromatograph is equipped with a flame-ionization detector, maintained at a temperature of about 260°, a splitless injection system, and a 0.53-mm × 30-m fused-silica capillary column bonded with a 1.0-µm layer of phase…
Hello howard_sanford ,
I tried clearing the preferences for IDBrowser, and it did work when I used the old PCDL, but the "m/z" column in ID Browser did not show anything. So, I did it again and for the second time, the m/z of features showed up, but…
In my experience, usually when a method fails to download to a 7820A GC it means that one of the zones on the GC is in a faulted state. This does not always get reported in the instrument actuals in ChemStation, so the best way to double-check this is…
The universal VUV detector has sensitivity better than an FID and similar to an MSD while allowing data acquisition across 12 different wavelength bands to focus on selected compounds of interest. It can be mounted directly on top of an Agilent 7890 or…
