Avance Neo 700 is equipped with a 5mm helium-cooled broadband cryoprobe optimised for X-nuclei in the range 15N (71.0 MHz) - 31P (283.5 MHz), excluding 153Eu, 137Ba, 175Lu, 181Ta, 123Sb, 133Cs, 138La, 6Li, 209Bi, 75As, 171Yb and 199Hg. The second channel tunes to 1H and 19F.
The sensitivity specifications are:
1H sensitivity 4238 : 1 (>2900, noise [200 Hz], 0.1% Ethylbenzene in CDCl3);
13C sensitivity 2283 : 1 (>1800, noise [40 ppm], ASTM, 40% dioxane, 60% C6D6);
15N sensitivity 222 : 1 (>190, noise [2 ppm], 90% formamide in DMSO-d6);
19F sensitivity 4985 : 1 (>2600, noise [1 ppm], LB=2 Hz, 0.05% Trifluorotoluene in CDCl3);
31P sensitivity 1166 : 1 (>1000, noise [5 ppm], 0.0485 M Triphenyl Phosphate in acetone-d6).
There is also a room-temperature broadband probe, with the following sensitivity specifications:
1H sensitivity 1021 : 1 (>500, noise [200 Hz], 0.1% Ethylbenzene in CDCl3);
13C sensitivity 511 : 1 (>400, noise [40 ppm], ASTM, 40% dioxane, 60% C6D6);
15N sensitivity 75 : 1 (>50, noise [2 ppm], 90% formamide in DMSO-d6);
31P sensitivity 299 : 1 (>200, noise [5 ppm], 0.0485 M Triphenyl Phosphate in acetone-d6);
The instrument uses a 60-position sample changer and is typically operated under automated control.
This 700 MHz NMR spectrometer was funded by EPSRC, UCL and Simons Foundation in 2017.
