Dear User The probe has been fitted with a totally new Automatic Tuning and Matching hardware assembly as part of its refurbishment.  This means that, when you run the ‘atma’ command and if the solvent that is used with your sample has not been already ‘registered’ in the probe’s database, it takes a while to […]

Dear Users Afte a long wait, the probe which has undergone a thorough (and expensive) overhaul is back in the AV300 magnet.     With a noble motivation to provide immediate access to this more convenient probe,  I have done a ‘quick and dirty’  install of the probe and I am releasing the same for regular use.

The ATMA probe’s functionality worsened further and so the eventuality I talked about came sooner.  The Probehead has been pulled out for repairs and it is early times to tell if the same probe will be back in the magnet within a day. What to expect :  We will either place the fixed ATMA probe […]
