ALERT ! GG500 – iPROBE NOT READY YET
Dear Users Fresh from the expensive repair, the iProbe is not delivering what it promised. Although you might see Topshim seem to complete it’s job, digging deeper, it is clear that the shimming is not at an acceptable level. Since we have a narrow window of warranty for such repairs, it is imperative that we […]

ALERT ! GG500 – iPROBE IS BACK – PROBE CHANGE TODAY
Dear Users We usually provide a day or so, when a probe swap is planned in a given instrument. This is usually the practice when the swap is done for benign reasons. An example will be moving from BB (BroadBand) capability to a specialized capability such as only-19F observation. This usually gives the BB users […]

UPDATE – NEO500 : AUTOMATION QUEUE STARTED AGAIN
Dear Users Nothing more to add on the technical side of the instrument. But I do have something to add as to the handling of sample and the system. There is a ‘method to the madness’ and a ‘rationale behind a pesky insistence’, when me or Adrienne shout from the rooftop. (As I was writing […]

NEO500 – CALL TO ACTION – PLEASE CLEANUP AFTER YOURSELF !
Dear NEO500 Users This is a renewed call made a few weeks back about the piling up of unused/completed NMR sample tubes, that is overwhelming the system. See picture below : Since we don’t have a capacity larger than 24 sample tubes, we really need you to be on top of your cleanup act, […]

ALERT ! GG500 – POSSIBLE DAMAGE TO iPROBE – TXO PROBE IS IN ITS PLACE NOW
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 […]
