MAS controller

NMR Service offers a fully pneumatic controller unit to control and monitor MAS speeds. Please do not hesitate to contact us for details.

• To set MAS speeds with ±1 Hz precision
• Controls MAS speeds of up to 150 kHz
• Manual and automatic start/stop
• Frame cooling gas, insert and ejection gas (dry air or nitrogen gas)
• 0 – 4 bar drive and bearing gas regulation
• Requires min. 5 bar main pressure input (dry air or nitrogen gas)
• Maximum 8 bar main pressure input (dry air or nitrogen gas)
• Please note, the stability of the MAS speed might be influenced by the pressure stability of the input gas.
• Microcontroller-based TTL and analogue monitoring output
• Requires min. 50 mV peak-to-peak input signal from probe
• 24 set-ups for different rotor types
• USB connection to the PC
• Software to monitor spinning speed and stop spinning (requires Microsoft Windows 10)

Suitable for Bruker systems

• Plugs, connectors, signal in- and outputs fully Bruker compatible
