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!

Hello,
You will need to license the software before the 60 grace period ends, or some function will stop working until you have a permanent license. I do not know what configuration you have nor the purpose of the installation so I cannot say why…
Hello,
You turned the value back into a number by dividing by10 outside the formatnumber statement. I would just place the entire statement in a Val() function and then format the column as 1 decimal place.
