Welcome!
The NMR Facility has only one Entry (on the TA Auditorium side) and one Exit (next to the A400) for now.
There are four sectors -- (i) A1/NB3/cluster computers, (ii) A2/A3, (iii) A400, and (iv) A500, respectively -- for strict social distancing, one user at a time!
You MUST follow the path shown by the signs for in and out movement!
Signing up through our webpage using the WASE calendar for 10 minute blocks of time is required, multiple consecutive blocks are acceptable if needed, one empty block must be kept between users. No exceptions!
Regular PPE is required, no outside gloves from the lab are welcome!
You must use a new plastic sheet every time to cover the keyboard and mouse, discard it after finished! For touching spinners and tubes use kimwipes.
Personal communication should be kept at minimum, ask for assistance through the glass!
Phone numbers for quick access are 609-933-3528 (cell for István, for text, too) and 609-258-1633 (Ken's office).
The Department of Chemistry houses a world-class nuclear magnetic resonance (NMR) facility with outstanding instrumental power and experimental capabilities.
To request training, consultation, and/or assisted services, please contact the core director. The NMR Core Facility does not currently accept reservations via iLab, this page is for informational purposes only.
The NMR Core Facility is available 24/7 to fully trained and authorized users.
Staff assisted servicse are available Monday - Friday from 9am-5pm.
Instrumentation Available
NEO console, 3 mm TCI cryoprobe, 24 holder SampleCase autosampler, 800MHz
Highest sensitivity for proton detected experiments, triple resonance (1H/13C/15N) experiments, 2H detection and second for 13C detection. The 5 mm QCI-F cryoprobe is also available on demand.
1H, 19F, 31P, 13C, 11B and many other heteronuclei.
Two HR-MAS probes (4 mm rotors) are also available, one 1H/13C/15N and another one for 1H/13C/14N.
All proton detected experiments, triple resonance (1H/13C/15N) experiments, 2H detection and capable for 13C detection.
Direct detection of all heteronuclei with high sensitivity, quite good for 1H, too, 2H detection.
A 5 mm RT high-power diffusion probe (up to 1,700 G/cm gradient strength, water-cooled, H/F,31P-15N) alternating periodically on demand.
Unique for 13C detection (unparallel sensitivity), and very good for 1H as well.
Workhorse machine, also for very low temperature (-100oC) experiments.
Competitive for all heteronuclei from -40oC to +150oC
ssNMR/DNP instrument
This is a latest generation Bruker 400 MHz WB system with two probes for conventional ssNMR applications (using 3.2 mm and 1.3 mm rotors, respectively) and NEO console. One probe (3.2 mm) is a two-channel tunable multinuclear probe, the 1.3 mm probe is triple resonance with several nuclei available using inserts – the collection of nuclei is expandable. The maximum speed for the 3.2 mm rotor is 25 kHz, the 1.3 mm rotor was tested at 65+ kHz, which allows proton-detected sophisticated experiments.
Each probe has a wide range of temperature control.
In addition, the instrument has a DNP (Dynamic Nuclear Polarization) accessory with klystron-based MW source and two probes also (with 3,2 mm and 1.3 mm rotors, respectively). The DNP enhancement may exceed 100+-fold sensitivity increase, allowing drastic shortening of the experiment time or accessing low sensitivity nuclei or very small quantity samples. The default operation is at 100K using nitrogen cooling, supported by the latest, third generation temperature controller unit. The probes are multinuclear with inserts and at RT they can be used as conventional ssNMR probes as well.
All instruments are controlled by TopSpin 4.3/3.5pl7 software and can run a large variety of 1D and 2D/nD correlation experiments, water suppression is routine. The liquid state instruments are equipped with ICONNMR automation interface.
The default processing software MestreNova, NMRPipe recommended for nD experiments.
