UPDATE – AV301 : REPAIR PARTS ORDERED TO RESURRECT PROBE
Dear Users
The consistently poor shim performance and the related failure to lock on a solvent after Topshim, especially for weak solvent signals such as CDCl3 is due to broken parts inside the probehead.
Since this is the surrogate i.e. backup probehead, I do not have another backup probehead with Topshim capability to replace it immediately. Since the parts ordered should be here in a couple of days, I am hopeful to put the same probe back in the magent by Thursday.
If you remember, the original probe with ATMA and Topshim capability developed issues and that probe has been sent to the factory for repairs.
Stay tuned for further updates.
