Bruker Avance Neo 500

Check the queue on the 500 MHz instrument.

This instrument together with the broadband probe ¹⁰⁹Ag-³¹P/¹H (with z-gradients and auto-switch from one nucleus to another) and SampleCase+ sample changer is used mainly for ¹H and multinuclear measurements. 

The sensitivity specifications are: 

¹H  450 : 1 (noise [200 Hz], 0.1% Ethylbenzene in CDCl₃);
¹³C 280 : 1 (noise [40 ppm], ASTM, 40% dioxane, 60% C₆D₆);
¹⁵N  45 : 1 (noise [2 ppm], 90% formamide in DMSO-d₆);
 ³¹P 225 : 1 (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. These findings are of Dr Peter Simpson from Bruker UK.

The BACS 60 sample changer and Avance I console shown in the picture below were replaced by SampleCase+ and Avance Neo in January 2021.
