UPDATE ! GG500 : iPROBE IS PRIMED AND READY TO GO
Dear Users Thank you for your kind patience. The probe shims up great and for those of you who are curious, here is a snapshot of the 1D proton spectrum of the so-called Lineshape standard, i.e. 1% CHCl3 in Acetone-d6. The wiggly noise flanking the central singlet of CHCl3 are mostly due to floor vibrations […]

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 […]

Even the maintenance related reservations such as cryogen fills will have disappeared. For some Netid-s the reservation system allows you to block time and for most […]

Since the issue needs careful analysis, instead of blocking the instrument, it is releasd for routine use immediately. You might see the calendar blocked intermittently in the coming […]

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 […]
