[Rajkumar Agarwal]

As you want to know about Indian Institute of Technology Bombay, Nuclear Magnetic Resonance Spectrometer here I will get details for you.

Details
Make : VARIAN, USA

Model : Mercury Plus 300MHz NMR SPECTROMETER

Specification :
5mm Autoswitchable probe with PFG (1H/ 13C/ 31P/ 19F) 5mm Dual Broad Band probe with PFG for Multinuclear NMR (13C, 15N, 27Al, 31P, 29Si, 77Se, 119Sn, 125Te, 199Hg, 51V, 7Li etc.)

MAIN FEATURES OF THE INSTRUMENT
MAKE : VARIAN, USA.

MODEL : Mercury Plus 300 NMR SPECTROMETER.

Specification : 5mm multinuclear probes for solution studies. Multi nuclear CP-MAS probe for solids application.

VT Accessory: Variable temperature facility is available from -80 degree to +130 degree with suitable solvent.

The NMR Probe is switch-able between high frequency range (1H, 19F) and broad band frequency range (13C, 15N,

27Al, 31P,29Si, 77Se, 119Sn, 125Te etc.).

In case of solids, only broad band frequency range is available and the sample can be spun up to a maximum of 5KHz at the magic angle.

High power decoupling in case of solids is limited to a power of 100 W.

Total spectral width is limited to 100 KHz.

User Instructions
1. Users are advised to provide 10-20 mg of sample depending upon its molecular weight for obtaining high resolution proton NMR spectra.

2. The sample should be completely soluble in 0.6 cc of the given solvent.

3. For 13C at least 30 mg of sample is necessary for obtaining spectra with reasonable signal / noise ratio. However, higher amount of sample helps in reducing data acquisition time which in turn leads to reduction of analysis charges.

4. For MAS-NMR experiments, sample should be in the form of very fine powder (20 microns) and at least 4.0 cc of powder is required.

5. All external users are required to submit samples accompanied by a letter containing analysis details.

6. Users from Bombay and its surroundings may contact NMR Laboratory for advance appointments, if so desired.

7. While requesting for analysis, information on i) type of analysis, ii) solvent and iii) spectral range should be given clearly in the letter.

8. Users are encouraged to be present during the analysis of their samples. Users who are interested in specialised experiments are advised to contact NMR Laboratory for an appointment. All users are required to acknowledge the use of the facility when the results are published or presented in a symposium / conference. It will be highly appreciated if users send a Xerox copy of such publication/report to the NMR laboratory, SAIF, IIT, Mumbai. 400 076.

9. All samples should accompany material safety data sheets (MSDS).
