There are no fixed publishing dates for this newsletter; its appearance solely depends on whether there is a need to present information to the users of the spectrometers or not.
An Agilent 7510-AS autosampler with 12 sample positions, has been installed on the u500. After some time and effort, the software has been modified to incorporate the u500 with autosampler into the EZNMR system. On May 22, 2012 the u500 will be operated with the autosampler.
general access: robot operation
Study times on the u500:
The above numbers indicate that the u500 with cold probe offers a factor of 6 improvement in sensitivity for both H1 and C13 over the ibd5. This improvement translates into time savings by a factor 36. In other words, to achieve the same signal to noise ratio as a 30 min 1D C13 experiment acquired on the u500, the same experiment must be run for 18 hours (generally an overnight acquisition) on the ibd5.
Generalized safety information for users working in the NMR facility is now available here. A link to the safety material has also been placed on the main web page for this site for ease of access.
