PLEASE NOTE ! NMR LAB DOOR CARD READER IS MALFUNCTIONING
I have left a wooden wedge to prop the door open as a temporary measure, since most of you may not have a physical key to open the door. Please leave the wedge as it is, until we fix the door problem. Thank you NMR Facility Manager 2/12/2020

UPDATE ! AV300 : FROZEN TOPSPIN SCREEN REMEDIED
The cause of the frozen screen upon login is this : When there is no dataset that is already open in the spectrum display area (blue tile), we usually drag and drop an existing dataset into it. For some reason that has to do with the way the Display system and Topspin interact, this causes […]

UPDATE ! AV500 – SYSTEM BACK TO NORMAL OPERATIONS
There are two updates to be highlighted here : AV500 is back to a three channel configuration after an (expensive) replacement of a failed circuit board. You can therefore plan {1H, X, Y} type experiments. The TBI-1H {13C,X} – Z gradient probe has been placed back in the magnet. This probe has a dedicated 13C […]

UPDATE ! AV500 – INTERIM SOLUTION IN PLACE
While we are waiting for replacement of the compromised circuit board, we have patched this unit together to function as a two-channel instrument. The BBI-Z gradient probe is paired with this so that you can pulse two nuclei at a time i.e. 13C with 1H decoupling OR 31P with 1H decoupling, as examples. In a […]

UPDATE ! AV300 : AUTOMATION SCRIPTS…
If any of you have been trying to use the automation scripts on AV300, you might have encountered repeated failures, with some cryptic message that ends in “core dumped”. This obscure problem was related to a software bug and that has been squashed now. Commands of the type ‘multizg’, ‘iexpno’, ‘multicmd’ are a few examples […]

ALERT ! AV700 – MOVED FROM SOLIDS TO SOLUTION STATE
With due apologies for this very short notice, I am glad to address the solutions users that the AV700 system is now sporting the BBO probe with Z-gradient capability and ready for regular use, shortly. But for a block of time that I reserved for a time-sensitive run for a user, the instrument should be […]
