VARIABLE-TEMPERATURE NMR on the Varian Inova-400, 500 and VXRs-300

Varian NMR变温实验操作。

Notes on Variable Temperature
IN AN EMERGENCY:

If the power fails, the gas supply is interrupted, you notice a burning smell, etc., IMMEDIATELY STOP ALL VT ACTIVITIES:

1. Immediately type temp='n' su

2. Immediately set the FTS pre-conditioning unit to 20C.

3. Immediately remove the liquid nitrogen bucket if you are using it.

4. Immediately contact the NMR Facility staff.

5. Immediately remove your sample.

6. In extreme emergencies:

A. Walk around the magnet to the back of the I-400 console. DO NOT walk between the magnet and console through the cables & circuits.

B. Turn OFF the power to the VT unit by pressing the big red "POWER" button on the console VT unit (the console VT unit has a black panel with a POWER button, STATUS light, and LED display of the temperature).

1。Troubleshooting the VT unit.
2。To perform VT experiments between +25C and +90C:
3。To perform VT experiments between -35C and +30C:
4。To perform VT experiments between +90 and +150C
5。To perform VT experiments from -120C to +0C:
6。To Accurately Measure the Temperature:
7。Important Notes about VT:
