Hello,
This one could be difficult. 2 things come to mind. First make sure you are not saving the folder of the batch into another batch folder. This will void the .b folder and failed to read correctly. Go see if you can into the drive X:Agilent\ICPMS…
Once the lamp got ignited the light arc between anode and cathode has been sustained.
The referring anode voltage typically stabilizes after a certain time and can be heavily influenced by environmental conditions.
Fluctuations in the anode voltage…
Thank you Kbusch.
Is there any videos that can show me how to move needle arm out of the seat. I tried to go through Lab Advisor but the arm does not go to maintenance mode. Lab Advisor timed out and failed to connect to LC. I shut down the sampler…
Hello collrube ,
No such thing as a dumb question
Just so I can understand the question better, do you mean that you used to have a 5890 GC FID system, and you replaced that with an 8890 GC FID system? Or do you mean that your FID on the 5890…
Dear all,
we have not measured many samples, only some organic samples. Could someone please explain, what cause the RF coils change the color like this? Does it affect the plasma ignition? How to clean it properly?
Is it correct, I take the coils…
Hello SimonHarries ,
The only time I have heard an FID trying to re-light itself is when the baseline of the FID dropped below the Lit Offset value.
What is your baseline at (in pA) when the FID is lit, but not running sample? And what is your lit…
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…
May I ask? Did you take an official FLD training? Working on the innards of an FLD usually is for trained staff only. Many things can go wrong here, e.g. replacing the lamp is much different to replacing the lamp on a UV detector. One can screw up the…
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…
