Riddle me this. We've encountered a rather strange phenomena when optimising MRM transitions on a Agilent Ultivo TQ. The MS does not have any issues in generating the precursor ion for example 897.5 (216V fragmentor) but fail to generate a product ion…
Hi All,
I am experiencing a configuration issue with a new Thermo Fluorescence Detector installation on a 1200 series LC with OpenLab CDS 2.5. After installing the SII 1.2 Software for the FLD, I try to configure the FLD with Chromeleon, however I am…
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…
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…
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…
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 everyone, This is my first post and I'm excited to have discussions for this thread. I wanted to start off with a small introduction with some of my experience. I have 4 years of experience in operation, maintenance, method development on the following…
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…
