The restriction capillary is put in place of the column, to protect the column and run a wear in procedure after replacing the pump seals. Or to flush the system during tests. Do you still need assistance with your request?
luciayuan Why DMF cannot go through channel D? Which pump do you have? Isocratic or Quaternary pump? For the leak rate test, I would suggest pressurize the pump at the purge valve to find out where it is leaking. I would suggest log a ticket with your…
At this time there isn't any UV deconvolution in our software. We do offer LCMS Deconvolution/Bioconfirm. Mass Spectrometry Deconvolution Software – OpenLab CDS | Agilent
MSCHU I would suggest reinstall the peristaltic pump and ensure there is flow to the seal wash sensor (top right). If not, please reach out to the local Agilent representative for technical support.
Hello,
No, you would need to have the original method used to acquire the data, already have a calibration or at least have the compounds identified.

Hi LD,
We do not recommending substituting as EGTA has higher affinity for chelating calcium ions and lower affinity for chelating Mg2+ ions compared to EDTA.
Thank you and please let me know if you have any other questions!
