Dear Users We swapped the probe today to BBO as a one time process to access a rare nucleus.  Those of you who will use the instrument over the weekend, please note that, this a BBO Probe that includes 1H and X-nuclei coverage, that includes 13C. What you WON’T have is 19F capability. We will […]

Dear Users As I announced last week, the ailing ATMA probe has been pulled out and in its place, the good old TXD probe is placed and primed up.   This probe has three dedicated channels for 1H, 13C and 19F. THIS IS NOT A BROADBAND PROBE ! This means that you cannot observe anything other […]

A user sample has broken inside the magnet and the sample Lift function is compromised. I will post an update once the broken sample is removed and the function tested to be normal again. NMR Facility Manager 10/28/2021

Dear Users Many of you might recall the look and feel of this Triple Resonance TBI probe when it was placed with the AV500 system, before GG500 was born.   It won’t hurt to have a refresher and familiarize oursleves with this probe, which is now paired with GG500 console. 1H NMR : The picture below […]

Hello Users ! We have done a ‘deep cleaning’  of the sample handling system yesterday and the results speak for themselves.  The sample lands properly and it is detected correctly by the system. The Sample Spinning settles to its target rate pretty quickly now. We also have shimmed up the system and so it should […]

Dear Users GG500 is now ready for routine use with the TBI triple resonance probe in place, calibrated and optimzied. I am also glad to add that the VT  control is completely restored now so that you can run temperature variation experiments.  The nominal range is about -10 C to 70C but I will give […]
