Model CS350 single channel potentiostat galvanostat can be used in battery study,Website:, energy and materials, such as fuel cell, Li-battery, coin battery, perovskite solar cells, supercapacitor etc. The most common electrochemical methods or battery test include Cyclic voltammetry, constant current charge and discharge, EIS etc.It contains a fast digital function generator, high-speed data acquisition circuitry, a potentiostat and a galvanostat. With high performance in stability and accuracy with advanced hardware and well-functioned software, besides battery test, it is also a comprehensive research platform for corrosion, electrochemical analysis, sensor, life science and environmental chemistry etc.HARDWARE FEATURESDual-channel high-speed 16bit/high-accuracy 24bit AD converter;Built-in frequency response analyzer(FRA), frequency range: 10µHz~1MHz;High-bandwidth high input impedance amplifier unitBuilt-in FPGA DDS digital signals synthesizerHigh-power Potentiostat/Galvanostat/ZRA;Potential control range: ±10V; Compliance voltage: ±21V;Current control range: ±2A;Potential resolution: 10µV; current resolution 1pA.SOFTWARE FEATURESCS studio software provides users a versatile smoothing/differential/ integration kit, which can complete the calculation of peak height, peak area and peak potential of CV curves.CS Studio software can achieve real time saving of the measuring data. The data can be automatically saved even in case of sudden power off.CS studio kit has a built-in versatile timing policy for combined measurements, which can facilitate the automation of experiments and save time.Battery analysis: charge & discharge efficiency, capacity, specific capacitance, charge & discharge energy etc.EIS analysis: Bode, Nyquist, Mott-Schottky plotTECHNICAL ADVANTAGES1. Impedance (EIS)CS350 potentiostat applies correlation integral algorithm and dual-channel over-sampling technique, and has strong anti-interference ability. It is suitable for EIS measurements of high-impedance system (>109O, such as coating, concrete etc.). It can also be used to obtain Mott-Schottky curve and differential capacitance curve. During test, the software can display real-time open circuit potential(OCP) without entering.             EIS of AA6063 Al alloy in Ce3+ containing 3% NaCl solutionPolarization curve of Ti-based amorphous alloy & stainless steel in 3%NaCl solution2. Polarization curveIt can complete linear polarization curve and Tafel plot measurements. The user can set the anodic reversal current (passivation film breakdown current) of the cyclic polarization curve to determine material’s pitting potential and protection potential and evaluate the its susceptibility to intergranular corrosion. The software employs non-linear fitting to analyze polarization curve, and can make fast evaluation of material's anti-corrosion ability and inhibitors.3. Voltammetry It can do the following electroanalysis methods: Linear Sweep Voltammetry(LSV), Cyclic Voltammetry(CV), Staircase Cyclic Voltammetry(SCV), Square wave voltammetry(SWV), Differential Pulse Voltammetry(DPV), Normal Pulse Voltammetry(NPV), AC voltammetry(ACV), Stripping voltammetry etc. It integrates calculation of peak area, peak current and standard curve analysis.     LSV curve: mesoporous carbon material in 0.1M KOH          CV curves of PPy supercapacitor in 0.5 mol/L H2SO44. Electrochemical NoiseWith high-resistance follower and zero-resistance ammeter, it measures the natural potential/current fluctuations in corrosion system. It can be used to study pitting corrosion, galvanic corrosion, crevice corrosion, and stress corrosion cracking etc. Through noise spectrum, we can evaluate the inducement, growth and death of metastable pitting and crack. Based on calculation of noise resistance and pitting index, it can complete localized corrosion monitoring.Electrochemical noise of low-carbon steel in 0.05mol/L Cl-+0.1mol/L NaHCO35. Full floating measurementCS350 potentiostat galvanostat uses full-floating working electrode. It can be used for autoclave electrochemical measurements, on-line corrosion monitoring of metallic components under the ground (rebar in concrete, etc.) 6. User-defined methodsCS350 potentiostat galvanostat supports user-defined combination measurements. The user can set cyclic  timing measurements of an electrochemical method or several methods.We are able to provide API functions and development examples, which facilitates some users’ requirements for secondary development and self-defined measurements.Specifications Support 2-, 3- or 4-electrode systemPotential control range: ±10VCurrent control range: ±2APotential control accuracy: 0.1%×full range±1mVCurrent control accuracy: 0.1%×full rangePotential resolution: 10µV (>100Hz), 3µV (<10Hz)Current sensitivity: 1pARise time: <1µS (<10mA), <10µS (<2A)Reference electrode input impedance:1012O||20pFCurrent range: 2nA~2A, 10 rangesCompliance voltage: ±21VMaximum current output: 2ACV and LSV scan rate: 0.001mV~10,000V/sCA and CC pulse width: 0.0001~65,000sCurrent increment during scan: 1mA@1A/msPotential increment during scan: 0.076mV@1V/msSWV frequency: 0.001~100 kHzDPV and NPV pulse width: 0.0001~1000sAD data acquisition:16bit@1 MHz, 20bit@1 kHzDA Resolution:16bit, setup time: 1µsMinimum potential increment in CV: 0.075mVIMP frequency: 10µHz~1MHzLow-pass filters: Covering 8-decadePotential and current range: AutomaticPC and O/S requirementInterface: USB 2.0Operating System:Windows 2000/NT/XP/ win7/win8/win10Weight / MeasurementsNet weight: 6.5kg Gross weight: 10kgInstrument size: 36.5 x 30.5 x16cm; After package: 52.5 x 37.5x 22.5cmElectrochemical Impedance Spectroscopy(EIS)Signal generatorFrequency range: 10µHz~1MHzAC amplitude: 1mV~2500mVDC Bias:-10~+10VOutput impedance:50OWaveform: sine wave, triangular wave and square waveWave distortion:<1%Scanning mode: logarithmic/linear, increase/decreaseSignal analyzerIntegral time:minimum:10ms or the longest time of a cycleMaximum:106 cycles or 105sMeasurement delay:0~105sDC offset compensationPotential automatic compensation range:-10V~+10VCurrent compensation range: -1A~+1ABandwidth: 8-decade frequency range, automatic and manual settingSoftwareTechniques / electrochemical methodsCS310CS350Stable polarizationOpen Circuit Potential (OCP)vvPotentiostatic (I-T curve)vvGalvanostaticvvPotentiodynamic(Tafel plot)vvGalvanodynamicvvTransient polarizationMulti-Potential StepsvvMulti-Current StepsvvPotential Stair-Step (VSTEP)vvGalvanic Stair-Step (ISTEP)vvChrono methodsChronopotentiometry (CP)vvChronoamperometry (CA)vvChronocoulometry (CC)vvVoltammetryCyclic Voltammetry (CV)vvLinear Sweep Voltammetry (LSV)vvStaircase Voltammetry (SCV) #vSquare wave voltammetry (SWV) #vDifferential Pulse Voltammetry (DPV)#vNormal Pulse Voltammetry (NPV)#vDifferential Normal Pulse Voltammetry (DNPV)#vACvoltammetry (ACV) #v2nd Harmonic A.C.Voltammetry (SHACV)vAmperometryDifferential Pulse Amperometry (DPA)vDouble Differential Pulse Amperometry (DDPA)vTriple Pulse Amperometry (TPA)vIntegrated Pulse Amperometric Detection (IPAD)vEISEIS vs Frequency (IMP)vvEIS vs Time (IMPT)vvEIS vs Potential (IMPE)(Mott-Schottky)vvCorrosion testElectrochemical Potentiokinetic Reactivation(EPR)vvElectrochemical Noise(EN)vvZero resistance Ammeter (ZRA)vvBattery testBattery charge and dischargevvGalvanostatic charge and discharge(GCD)vvExtensionsData LoggervvElectrochemical stripping/depositionvBulk electrolysis with Coulometry (BE)vv# There is corresponding stripping voltammetry method.What the customers say Corrtest potentiostat "I am writing this letter to recommend this service of M/S Wuhan Corrtest Instrument Corp., Ltd to you.
