Multi Autolab/M204

The Multi Autolab/M204 is the newest addition to the SPECIFICATIONS

Multi Autolab/M204

Autolab series instruments.

The new Multi Autolab/M204 system is based on a user-

• Electrode connections 2, 3 and 4

confi gurable multichannel cabinet which can accomodate

• Potential range

+/- 10 V

up to 12 M204 potentiostat/galvanostat boards.

• Compliance voltage

+/- 20 V

The M204 is a 20 V/400 mA potentiostat/galvanostat,

• Maximum current

+/- 400 mA

fi tted with a built-in analog integrator and with analog

• Current ranges

100 mA to 10 nA,

and digital input/outputs which can be used to interface in 8 decades

to external instrumentation.

• Potential accuracy

+/- 0.2 %

• Potential resolution 3 µV

Furthermore, the Multi Autolab/M204 instrument can be

• Current accuracy

+/- 0.2 %

complemented by adding extra modules to extend the

• Current resolution 0.0003 %

functionality of individual M204 boards. This provides the (of current range)

means to customize each channel for a specifi c electro-

• Input impedance

> 100 GOhm

chemical measurement.

• Potentiostat bandwidth 1 MHz

• Computer interface USB

Optional modules

• Control software NOVA

• FRA32M – Electrochemical impedance spectroscopy

• pX1000 – pH and temperature measurements

• MUX – Multiplexing module for complete cells or individual working electrodes

• BA – Dual mode bipotentiostat

• EQCM – Electrochemical quartz crystal microbalance Dedicated to research www.metrohm-autolab.com

Autolab RRDE

The Autolab Rotating Ring Disc Electrode (RRDE) is the SPECIFICATIONS

Autolab RRDE

latest addition to the Metrohm Autolab accessories for electrochemical measurements.

• Speed control

Manual or by NOVA

The Autolab RRDE can be used to perform electrochemical software

measurements under controlled hydrodynamic conditions.

• Motor speed range 100 – 10,000 RPM



+/- 1 RPM

The Autolab RRDE uses 2 identical friction-less mercury

• Acceleration/deceleration 4,000 RPM/s

contacts for ultra-low noise measurements and can be

• Maximum disc current 500 mA

used with any Autolab potentiostat/galvanostat fi tted with

• Maximum ring current 50 mA

the BA, dual-mode bipotentiostat module.

• Contact

Double sealed Hg pool

• Electrode tips

Pt disc/Pt ring,

The Autolab RRDE is provided with a motor controller that Au disc/Pt ring,

can be operated manually or by the NOVA software. The GC disc/Pt ring

rotation rate can be specifi ed between 100 RPM and

• Collection effi ciency 24.9 %

10,000 RPM in 1 RPM steps.

• Electrode gap

375 µm

The Autolab RRDE electrode tips are fi tted with a 5 mm electrode disc and a thin concentric platinum ring.

The electrode disc is availalble in Gold, Platinum or Glassy Carbon. The RRDE electrode tips are dimensioned with G, CH-9100 Herisau

an electrode gap of 375 µm and a theoretical collection ohm A

effi ciency of 24.9 %.
