Single-Tuned 4mm Cryocoil MAS Probe

A tunable single-tuned 4 mm Cryocoil MAS probe was  developed, and demonstrated for ⁶Li and ²⁹Si under 14.1 T  WB magnet. The sensitivity enhancement factor attained by  the Cryocoil MAS probe is 4.4 times compared with the same  experimental condition using the conventional probe.

Typical Specification:

• Detection Coil Temperature: 14 K
• Sample Temperature: 273 - 353 K
• Rotor O.D.: 4 mm  (volume: 50 ul)
• Spinning Speed:  18 kHz max.
• Tuning Range: 73 - 192 MHz
• Input Power:   250 W max.
