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 […]

UPDATE ! AV301 – LOGIN ISSUE IS RESOLVED

The login issue that users noticed is linked to a network outage problem with UW Udrive resource.  As I write this, IT connect has not yet resolved this. So, we have fenced off the cause of the frozen login at our end and users can now login to the system as before. The UDRIVE cloud […]

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 […]

AV700 – UPDATE : SYSTEM IS BACK IN OPERATION (WITH CAVEATS)

The BBO – Z gradient probehead is in place, optimized and ready for use.  Please remember that you CANNOT reach below 273 K (0 C) with the current setup.  You can go higher in temperature as before. If you are wondering,  in a nutshell, we had to deal with two solution NMR probe heads that […]

UPDATE ! AV500 – SYSTEM IS UP AND RUNNING

SYSTEM IS UP ! Thank you for your kind patience during the down time. I shall post a detailed message about VT in a following upload. For the present : The temperature system is working as expected. The noise that people had seen on the baseline, should no longer be there. I will end with […]

UPDATE – AV500 – SYSTEM WON’T BE READY UNTIL TOMORROW – FRIDAY

I apologize for this discouraging news but the temperature control is not functioning as expected and as I write this, the issue is being addressed actively.  If the problem is deemed to take more time to fix by tomorrow, I will release the instrument for use, after highlighting caveats if any.  Please pay attention to […]
