UPDATE ! AV500 – SYSTEM NORMAL WITH BBI PROBE IN PLACE
NEW PROBEHEAD IN PLACE ! CURRENT PROBE : BBI 1H {X} – Z gradient DEFAULT SHIM SET : stdbbi Temperature range : -100 C to +70 C (for the former, special low T setup is needed. Contact for further details) PLEASE USE TOPSHIM FOR GETTING THE BEST RESOLUTION AND LINESHAPE Questions/Comments/Help ? : Please contact […]

ALERT ! AV500 – POSSIBLE PROBE CHANGE – VT DEWAR DAMAGED
The VT dewar inside the probe has been compromised and so you CANNOT run Variable Temperature experiments currently. ONLY nominal room temperature experiments are allowed at this point. We will most probably place a different probehead in place of the current HCP-Z Gradient probehead while the current probehead is serviced. We will try to do […]

UPDATE ! AV700 : SYSTEM IS RELEASED FOR USE – PLEASE READ
The system is ready for normal use. Nevertheless, the VT system test is still being conducted in parallel in such a way that the users’ runs are not affected. As before, the LN2 tank you see is the source of the N2 gas, which is used as part of the troubleshoot process. The supply from […]

ALERT ! AV301 – SYSTEM DOWN DUE TO COMPUTER ISSUE
We are working actively to resolve the issue and will post an update once the task is competed. Other than the ‘udrive’ mounting problem, we are also aware of the acquisition error messages that was noticed by users. Hopefully, both these error conditions will be resolved at the same time.

AV700 – UPDATE ON VT SYSTEM STATUS
As part of an ongoing investigation of the ultra low temperature chiller system, users are alerted to the following. You will notice a Liquid Nitrogen Dewar sitting next to the Aluminum staircase. The N2 gas derived from this tank is used currently to run the VT system. This setup is transparent to the way VT […]

UPDATE : AV700 USERS – SYSTEM READY FOR USE
The BBO-1H{X}-Z gradient probe is in place now. Please Remember: After creating a dataset, do ‘edsp’ to re-initialize the new base frequency. Load the default shim file : stdbbo and then start the shimming process. NMR Facility Manager 6/4/2018

ALERT ! AV700 USERS : IMMINENT PROBE CHANGE – Monday, 4 June ’18
The current 1H sensitive TXI-HCN probe will give way to the BBO-Z-gradient probe. This probe is optimized for X-nuclei but also capable of 1H observe. The probe swap will occur on Monday the 4th of June 2018 forenoon. After the preliminary checks, the system should be ready for regular use by noon. Please contact me […]
