Hello cjwwfd ,
B.06.00 is out of support at this point, but I can offer some general suggestions for current revisions and hopefully you can apply them to your version. Version 12.0 is the current release. If possible, I would investigate your options…
I'm experimenting the same error. Logbook displays <MSQQQ_1: QqQ fault detected: 1.23 vacuum system is not ready. This is typical during a pump down cycle or when the high vacuum pump is turned off during a vent cycle or fault condition>. Does anyone…
Hello DET ,
Sorry for the late response on this.
What sort of spiking do you see usually? What is the output of the FID, in pA?
Are you using any UPS systems, or are the GCs plugged directly into the wall?
Hi, I think it would be a good idea to upload your startup tune report in order to help you better.
Also I think you could take advantage of reading this post: https://community.agilent.com/technical/atomic-spec/f/forum/470/icp-ms-manual-tuning
Hello,
So, file based workstations store the full path to the methods in the sequences. If there is any change between the systems in the project path this is the expected behavior if you copy a sequence. If you open the sequence, browse out and find…
Hello guys,
I recently discovered, that it is possible to change your font properties in the injection list via shortcut (ctrl + b for "bold" and so on..).
Therefore I wanted to ask you, if there is some code for changing font types for CCF outputs…
Hi Mai,

Please check:
if the data file you are trying to open was generated using TapeStation security module as that can be one reason for the file not to open and error out.
If anyone…
