Hi Justin,
I have seen the same thing as you but with a standard length J-Young tube and
manual sample insertion. I agree with Clemens that altering the lift tuning
may be helpful. You may also want to check the hold sample airflow value in
the lift control section. You can get to these parameters by entering ha on
the topspin command line and then clicking on the open button next to lock\shim\vtu.
The main menu will appear, then click on sample handling. On the sample handling
page you can go to lift tuning or lift control. You might compare the lift
tuning and lift control values on the two spectrometers that you mentioned and
see if there are any differences that could explain why one works well and the
other doesn't. If you want to change any of the lift parameters you will have
to be logged in to ha as service. I don't know what the Bruker policy is about
posting the service login name and password so I won't do it here. Perhaps
someone at Bruker could comment.
Best,
Jeff

HI Justin,
yes J-Young or LPV tubes are top heavy. Do you have a Kel-F spinner? those
have a but more mass and might work better.
the other options is lift tuning. I would have to look up the exact how to.
But maybe _at_Groves.Michael can join in.
I would suggest a faster decent and shorter hover time if possible.
Clemens
