Hi everyone,
I've an issue with the fragment analyser (5200) my migration is aborted because the µA target is not achieved (4 instead of 5-1500µA).
The error log is called "HV supply" and I've notice that the little light "HV ON" is not turned on…
Thank you for your help! I will definitely keep in mind. Where is the small and large cover? I will look for the switch breaker at the back. I think it might be the Ar problem, during the 2 to 3 ignitions, the pressure meter on the Ar cylinder dropped…

I have a first order calibration with no evidence of any issues (%RE are small and random), but the end client has asked for a 1/x weighting to be…
Hello, I've been using an infinity 1260 autosampler and sporadically during injection I get the error: "Sampler G1329B:DEAAC21082 - Valve to bypass failed [EE 4014, 0]. This causes the system to disconnect and terminate the run. I can restart the entire…
Hi,
When self test on DAD G7117C with 10mm MaxLight Flowcell is performed, it fails because of the spectral flatness (measured 3.3587 AU and limit is 0.002 AU).
Whats exactly calculated in spectral flatness? What could be a reason that this test fails…
Hello what9000 ,
I have a couple questions to try to understand this better:
- What is the outlet voltage?
- Is it a dedicated circuit?
- Are you using any UPS systems, or is the system plugged into the wall directly?
We want to connect the output of one column to a splitter and then connect the outputs of the splitter to an MSD and a FID. Is that possible? The MSD worksin vacuum and FID toatmospheric pressure, then the effluent will be sucked by the MSD and there…
Hello E_Johnson ,
I’m sorry for the delayed reply to your message.
Thank you for asking this question. Always refer to the applicable Agilent instrument safety information when performing instrument maintenance or repair ( 7890 Series GC Safety Manual…
