Potentiostat/ Galvanostat with Accessories

• Should be fully computer controlled with complete digital data acquisition • Should work in POTENTIOSTAT, GALVANOSAT & EIS mode. • Should work in floating grounded mode when used in field / grounded cells/microbial fuelcell/ auto clave etc... Hardware specifications-Electrochemical system: • Compliance Voltage: 0 to 20V or more, • voltage Accuracy :0.1% &resolution @ 75uV or better • Current compliance: 100nA or less to 800mAmore, –- minimum 5 ranges should be provided-Accuracy @ 0.1% of the range or better. • Current resolution @ 1nA or better • EIS Freq Range: few uHZ to 1MHz , AC sine wave range: few mv to 2V • Electrometer input impedance: 100 GOhms or more • Electrometer Frequency bandwidth: 1Mhz of better • Future Up gradation to 50V & 100Amp must be possible. • Minimum 2 additional voltage recording input ( ADC ) for 0-10V range. Input received in this channel should be scalable and interpretable to control the software measurement protocols. (e-g: recording optical sensor info, Ph, Pressure sensor , LED light source info etc..) • Minimum one number of DAC ( 0-10V) to control the external devices from main system. Software requirements: • Voltammetry techniques- CV, Multiple CV, SWV, Staircase Voltammetry • Pulse: DPV, Normal Pulse, RNPV, Chronoaomperometry , Chronopotentiosmetry • Corrosion: Potentiostatic/Gavanostatic-Gavanodynamic, LPR, Tafel, ECN, CPT • Energy: charge/discharge Constant potential, Constant current, Constant power, Constant resistance/load, Calculation efficiency of cycle. • EIS: freq sweep – Log / linear, Sweep DC bias with freq • Software options should present to present the polarisation value against the externally acquired value • Software Fuelcell / Batteries / Super capacitor studies. • Complete analysis software for CV & EIS studies. System software should be able to control and acquire the data from external / third party make instruments. Cell kit and Accessories: • Oxygen free voltammetry cell kit with purge tube, volume not less than 20mL – with cap and electrode holder with at least 5nos cell vials. • Compatible Ag/AgCl Ref electrode/Pt counter electrode.
