Hello,
I would open a ticket with Agilent informatics support if your installation is client server based or your local Agilent support organization for workstation installation. They can typically help with issues like this where the data needs to…
Hello nikosmpik ,
You will need to go to your WIndows Services app and restart the service, make sure you set that to a Running status, and an Automatic startup type.
To get to the Services app you can do one of two things:
1. Press the Start…
Hello,
You need onsite visit. According to error 60304 and filament time this look like the power tube is too old and end of power life and need replacement.
Hi Metals.
I'm glad to see that you could solve the problem! And I'll take special note since our octopole has never been cleaned. We were told by Agilent that cleaning is meant to be done by Agilent's staff only. Thanks.
Yes, that solution of Ca…
Hi, the peak area has no influence on the calculation of Mw when measuring with concentration detectors only (RI, UV, ELSD e.g.). When performing Viscometry & Lightscattering measurements, the peak area is needed for the calculation. As an additional…
Occasionally the tune files get corrupted and you need to go back to an old one or start again from the default atune.u file. Glad the problem is resolved!
Part 1 included many questions and some answers about the maximum abundance that should be detected at the electron multiplier. Another important consideration is how much sample should go into the column.
See Which Electron Ionization Ion Source? Part…
