UW CHEMISTRY NMR

Hello All

Following an unfortunate incident of a user dropping the sample tube into the magnet bore without a spinner,  it turned out that the sample tube broke inside the new iProbe probehead.  Being a mint condition probe, which also belongs to the latest generation, it will need careful handling in assessing the extent of damage and the remedial measures that ought to be planned.

To minimize the instrument downtime I have placed the TXO-1H{19F,13C}-Z gradient probe as the surrogate. 

This is a familiar probe to all of you.  What more, this will replicate the outgoing iProbe’s capabilities of : (1) 19F observe with 1H decoupling and (2) running true 19F-1H double resonance experiments.

TOPSHIM is there !

You can use Topshim as usual to get the good resolution and lineshape without drudgery. But, remember, there is NO ATMA !  You must tune/match the probe by hand.

Of course, we will take all the necessary measures without delay to revive the iProbe to its original glory and put it in the magnet, as soon as possible.

As always, thank you for your cooperation.  The instrument will be released for reservation in the next ten minutes or so.
