ALERT ! GG500 – SYSTEM DOWN DUE TO SAMPLE HANDLING ISSUE
The sample eject/inject problem, led to the crash of the automation queue this morning. The system will be down until further notice to identify and remedy the issue. I will post an update once the queue is resumed. NMR Facility Manager 7.30.2025

UPDATE – NEO500 – PROBE IS FULLY FUNCTIONAL WITH TOPSHIM
Dear Users The probe is optimized for different lock solvents that should make shimming with Topshim quick and easy. I have created individual shim files that are the optimal starting points for the most often used lock solvents. The files are named as below : txo.water (for aqueous samples, including those in D2O) txo.acteone txo.cdcl3 txo.c6d6 txo.dmso […]

UPDATE ! NEO500 – PROBE CHANGED TO TXO-19F{1H,13C} – PLEASE NOTE
Dear Users The previous TBI probe had to be removed for a service operation, and I have placed the TXO-19F PROBE for the present as an alternative. Please note the following : Nuclei : 19F, 1H and 13C You can run 1H decoupled 19F experiments To switch between 19F and 13C, a cable swap is needed […]

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
