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…
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…
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…
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…
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…
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…
Hi there. I need your help. My gas sample is including hydrocarbons, CO and CO2, I was told I should used TCD detector, I used but there is no peak. I believe I need to use both FID and TCD detectors at same time and for that I need connector series between…

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…
