EA164_QuadStat
1Pages

(Model EA164) • Fully software-controlled • Applied potentials of up to ±2.5 V (or 10 V with external input) • Current range settings from 200 pA* to 1 mA* per channel • Current signal resolution 16 bits (0.0015% of range) • Suitable for use with amperometric biosensors • Can be used as a bipotentiostat • Compact! Use inside Faraday cages, or inert atmosphere boxes The EA164 QuadStat is a software-controlled, four-channel potentiostat. Each channel can be used as a single threeelectrode potentiostat, or two to four working electrodes can be used in a single reaction chamber with a common reference and auxiliary electrode. Potential at each working electrode can be independently adjusted between ±2.5 V, or by using an external waveform generator to between ±10 V. Single channel operation with EChem software: Normally supplied with 1 mA/channel maximum current, but optionally as a high current version with 10 mA/channel. Multichannel operation with Chart software: Compatibility Supplied ready for use with e-corder units (models ED821 or 1621 recommended) and includes electrode cables terminated with alligator clips. For Windows or Mac OS computers. • Cyclic voltammetry: compound characterization • Analytical chemistry research or teaching: differential pulse, normal pulse, square wave voltammetry, stripping techniques • Kinetics: pulse chronoamperometric techniques • Simultaneous monitoring of sensors in multiple reaction vessels • Bipotentiostat operation: two working electrodes with common auxiliary and reference electrode; also 3 or 4 working electrodes with common auxiliary and reference. • Sensors: use with amperometric sensors providing current signals down to the picoampere ranges • Neurochemistry: in vivo amperometry for neurotransmitter monitoring Specifications Maximum control voltage: ±2.5 V (±10 V with external input) e-corder filter settings: corder Maximum current per channel: ±1 mA (±10 mA on high current model) Bandwidth, unfiltered: Compliance voltage: >10 V >7.5 V on 5 mA range (high current model) >5 V on 10 mA range (high current model) Drift with temperature: Male and female DB-9 pin connectors. Provides control and power. Power requirements: (supplied by e-corder) Input resistance: Input bias current: Current range settings: Operating temperature: Current signal offset: ±500 µA* on ranges 2 µA – 1 mA* ±5 µA* on ranges 20 nA – 1 µA* ±50 nA* on ranges 200 pA – 10 nA* * Current values are increased by ×10 for high current model. eDAQ reserves the right to alter these specifications at any time.
