Bruker Avance Neo 500
A daily workhorse, which is also used for the initial training of users.
Check the queue on the 500 MHz instrument.
This instrument, together with the broadband probe 109Ag-31P/1H (with z-gradients and an auto-switch between nuclei) and the SampleCase+ sample changer, is used mainly for 1H and multinuclear measurements.
The sensitivity specifications are:
1H 449 : 1 (>330, noise [200 Hz], 0.1% Ethylbenzene in CDCl3);
13C 259 : 1 (>220, noise [40 ppm], ASTM, 40% dioxane, 60% C6D6);
15N 45 : 1 (>32, noise [2 ppm], 90% formamide in DMSO-d6);
31P 165 : 1 (>120, noise [5 ppm], 0.0485 M Triphenyl Phosphate (TPP) in acetone-d6).
Note that with the old Avance I console, the 1H sensitivity of the same probe was 285 : 1. This finding is of Dr Peter Simpson, who installed the Avance Neo 500 MHz console in 2021.
