UPDATE ! GG500 – AUTOMATION QUEUE RESUMED – CAN SUBMIT SAMPLES
Dear Users An improved automatic shimming algorithm via IconNMR is now in place. This should help, but it is part of the process that I need to complete, where solvent specific files need to be updated. That work will take place in coming days. Your resolution should be better, but if you see increased […]

ALERT ! GG500 – AUTOMATION PAUSED TILL NOON
Dear Users To address the repeated observations about non-optimal line shapes and shims, as well as to take care of few pending software tasks, the automation queue is stopped now. The instrument will NOT be available for submitting samples until then (please always consult the instrument reservation calendar, before proceeding to submit samples). At […]

ALERT ! NEO500 – TOPSHIM MALFUNCTIONING
Topshim is not performing optimization although the software goes through the motions. We are looking into it and will give an update as and when feasible. The shim system is alive i.e. you can shim the sample by hand if all else fails. We will keep you updated. NMR Facility 7.11.25

UPDATE ! AV700 – BBO SOLUTIONS PROBE IN PLACE
Dear Users Please note that the instrument is open for regular use after a brief interruption to investigate and optimize the VT system. Along with that task, we have now placed the Broad Band probehead in the magnet to give you the best possible senstivity for all X-nuclei, starting with 13C. As a refresher : […]

UPDATE – NEO500 – SYSTEM BACK TO ROOM TEMPERATURE PROBE
Hello All It will take more time to get the Prodigy Cryoprobe operational. As we speak, we are trying to get an additional failed component repaired/replaced as effectively as possible. To address the uncertainty of Prodigy’s return, we have once again installed the triple resonance TBI – 1H,13C,BB-Z gradient probe and the NEO500 is system’s […]

UPDATE : NEO500 – DELAY IN DEPLOYING PRODIGY CRYOPROBE
All Although all the needed components have arrived, we are still having issues in achieving the needed vacuum in the system (without which, the cryoprobe cannot function). The issue is being investigated. At the extreme, by tomorrow, the system will revert to the TBI room temperature probe and will be opened for routine use, while […]

ALERT ! AV700 – OPEN FOR SOLUTIONS NMR USE ! CALENDAR OPEN TO RESERVE
Hello All All of you have seen the exciting activity at one end of Rm. 37 from April onwards, when we re-installed the amazing 700 MHz system and guided it through some challenging stages of installation. The system has reached a happy equilibrium, and it is in prime shape to reward you with beautiful spectra […]

UPDATE – NEO500 : SHORT DELAY IN DEPLOYING CRYOPROBE
Dear Users We are waiting for a missing part that ought to have shipped from the manufacturer along with the repaired probe. It will be a few days before we are ready to install, test and release the Prodigy cryoprobe for regular use. To effectively use the time in the interim, we have put the […]
