We discovered a broken part in the TBI probe that made the 1H matching process untenable. While we are working on this, we have placed the triple resonance 1H{13C, 31P}-Zgradient probe in the magnet, as a temporary measure (hopefully).  We have every intention of returning to the excellent TBI probe once it is ready to […]

We are aware of reports from some users that the 1H matching rod is still not moving smoothly.  We will get to this as soon as possible and post an update of the results. NMR Facility Manager 1/29/2019

The probe mechanics are fixed to normalcy.  Please go ahead and use the instrument. Do not hesitate to post in the log book if you encounter difficulty. The tuning/matching rods, are near the magnet legs. They are no longer hanging from underneath the probe.  This will prevent accidental loosening of the screws in the probehead […]

The probehead issue I had mentioned last Friday might take more than a quick fix, upon inspection outside the magnet.   I have blocked the instrument until 11 am hoping that this will be done by then. Barring one,  I have retained the existing reservations on the calendar. If the situation changes, I will let you […]

Tuning and Matching glitch on 1H channel : The matching knob on 1H channel has lost its traction since it is mostly disengaged from the rod that rotates the matching Capacitor inside the probe.  We need to apply a minimally invasive remedy to fix this and we will do this on Monday, the 28th.  But […]
