2 Solid State NMR News Solid State DNP NMR 111 khz MAS NMR Adaptor kit for Varian and Chemagnetics probes MAS III firmware upgrades Application notes Training courses

3 Solid State DNP NMR Many applications in solid state NMR suffer from insufficient sensitivity Solid state DNP NMR today is the method of choice to solve this Biological systems (membrane proteins, fibrils etc.) Pharmaceuticals ( 13 C and 15 N 2D correlations at natural abundance Materials (frameworks, MOFs)

4 DNP of MOFs DNP-enhanced 15 N{ 1 H} CPMAS NMR spectra of UiO-66-NH 2 (a), UiO-66- NH 2 exposed to KCl (b), and Pt 2+ - loaded samples The NH 2 Pt peak grows linearlywith Pt loading of the MOF. Estimates of the ratio of free NH 2 vs. NH 2 Pt can be made based on the relative peak intensities in the NMR spectra.

5 Solid-State DNP NMR Spectrometer Gyrotron and Klystron Options DNP with Gyrotron Work in Progress: 263 GHz Klystron Offer a lower-price more compact microwave source at 263 GHz Design compatible with possible upgrade later to gyrotron for full power performance Power output ~ 5 W DNP with Klystron (EIK) Available 2017

6 111kHz - 0.7mm MAS Probe Highest available MAS rate High RF excitation in the 0.5MHz regime MAS stability of better than 0.25 at 111kHz (±28Hz max) 500nl Volume (350nl active volume) Available for SB/WB in HX / HXY / HCN configuration MAS 3 is mandatory!

7 MAS 3 High Accuracy MAS regulation for 0.7 mm Standard deviation less than 4Hz Long term stability for more than 7 hours tested
