ALERT ! AV301 – 31P TUNE/MATCH ISSUE
We are looking into the problem of ATMA and ATMM failing for the 31P selection. Initial tests show that the symptom might spread to the 13C channel with some lock solvents. The probe needs to be pulled out for further repairs. Once a back up plan is in place, we will announce the probe swap […]

UPDATE ! AV300 – ATMA AND ATMM STABLE
Quick recap : Many users found that 1H tuning/matching using ATMA or ATMM command did not behave as expected (either a flat wobble curve or no response to turning the tuning/matching capacitors in ATMM). Remedial measures are applied now. I expect the tuning/matching to behave properly for most of the commonly used lock solvents. Please […]

ATTENTION ! : INTRODUCING NEW STORAGE PARADIGM – UDRIVE
Moving with the times, we wanted to evolve a new storage solution that makes it robust, easy and secure to store and retrieve NMR data from the spectrometers. Such a solution should also be maintenance free, pretty much. This will free us all from the uncertainties of failing hardware and constant need for intervention from […]

ALERT : AV500 – TOPSHIM NOT FUNCTIONAL
Several of you have noticed that Topshim was failing. Currently, when you run Topshim, the software will not complain but the shims don’t change to give you a better lineshape or resolution. I have taken a preliminary look and will continue troubleshooting to run the problem to ground. As of now, you have to touch […]
