Departmental Instrumentation

Below is a summary of the six Departmental Bruker NMRs. Registered users may reserve NMR instrument time here.

NMR	Location in Havemeyer	Main Probe	Observe Nuclei	Special Capabilities	1H Sensitivity	13C Sensitivity	Most Common Experiments	Console type and software
500 Ascend	214	H/C/N	1H	sample changer	1000	100	HSQC NOESY HMBC, VT	AVIII single bay Topspin 3.0
500	208	BBFOplus	1H, 19F, 2H, X		650	290	13C, 19F, 2H, other X nuclei, HSQC NOESY HMBC, VT	AVIII single bay Topspin 3.0
400SL	208	TBO	1H, 19F, 2H, X	Solids, sample changer, Remote Control Possible	275	200	13C, 19F, 2H, other X nuclei, 1H, COSY, HSQC, VT, Solids	AVIII single bay Topspin 3.1
400L	208	BBI	1H		400	100	Short 1H, COSY, NOESY	AVIII nano bay Topspin 2.1
300NB	119	BBFO	1H, 19F, X		200	100	walk-on 1H	AVIII nano bay Topspin 3.0
300WB	208	BBO	1H, 2H, X		125	100	13C, 2H, other X	DRX Topspin 1.3

Variable-temperature range for all probes is -100 C to + 150C. All except the 300wb have Topshim gradient shimming and automatic tune and match (ATMA) of the probes.

Notes:

1. X means any nuclei except 1H, 2H, and 19F.. Sensitivity numbers are for standard samples (0.1% ethylbenzene for 1H and 40%/60% dioxane/d6-benzene for 13C) using the primary probe.

2. BBI and HCN probes are 1H optimized. HSCQ & HMBC are 1H obesrve type experiments and thus 1H optimized probes are ideal for these experiments. BBFOplus is X optimized but still retains good 1H sensitivity. BBFO and BBO probes are X optimized with comprimized 1H sensitivity.

3. The 500 Ascend, 400L and 300nb can NOT do 2H observe. 2H is only possible on 500, 400SL, and 300wb. 19F is possible on 300NB, 400SL, and 500.

4. We have a site license for MestreNova software for NMR processing and a data server from which data may be downloaded. There are also several workstations for data processing running Topspin in the NMR labs.

5. The 400SL was funded by an NSF CRIF grant and is Cyber-enabled. The 400SL NMR is available for remote-control usage and outside users are encouraged. Contact John Decatur for detailed instructions. Iconnmr or standard Topspin software may be used for control.

6. The 300NB and 400L have short time blocks available. The other NMRs have longer time blocks. See the rules here.

7. All NMRs except 300WB have pulsed field gradients.
