Preview:

Product Description Bipotentiostat/Bigalvanostat model CS2350M has two sets of independent potentiostat /galvanostat. The two channels can work together to conduct RRDE and hydrogen diffusion tests. In addition, each channel can also work independently in a complete electrical isolation mode. CS2350M bi-potentiostat is composed physically of two CS350M potentiostats. EIS function is included on both channels. Maximun current is +/- 1A on each channel. .Applications(1) Electrosythesis, electrodeposition (electroplating), anodic oxidation, electrolysis (2) Electrocatalysis such as Oxygen reduction reaction (ORR), OER, HER, CO2 reduction.(3) Li-ion battery, solar cell, fuel cell, supercapacitor, advanced function materials, sensor, etc (4) Corrosion behavior of metals, and anti-corrosion evaluation(5) Fast evaluation of inhibitor, water quality stabilizer, coating, and cathodic protection efficiency.Rotating Ring-Disk Electrode (RRDE)CS2350M can work cooperatively with the RRDE setup for the electrocatalysis study, such as LSV on the disk via channel #1 and LSV on the ring electrode via channel #2, to detect the intermediate products on the disk electrode.Hydrogen Diffusion Test (HDT)CS2350M can work with type H cells for hydrogen diffusion / permeating test. The H atoms diffusion coefficient in metal and hydrogen flux can be calculated by measuring the hydrogen charging current in the cathodic chamber and oxidation current in the anodic chamber. Faradaic efficiency testIn electrocatalysis, the Faradaic efficiency is measured to evaluate the performance of the catalyst. The cable connection is shown in below picture. A constant current will be applied on the disk and occur OER and produce oxygen. A constant voltage is applied on the ring and it occurs ORR and consume oxygen. The Faradaic efficiency can be calculated based on disk current and ring current.Specifications Specifications Support 2-, 3- or 4-electrode systemInterface: EthernetPotential control range: ±10V on each channelCurrent control range: ±1A on each channelPotential 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:1012Ω||20pFCurrent range: 2nA~2A, 10 rangesCompliance voltage: ±21VMaximum current output: ±1A in each channelCV 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: AutomaticWeight / Measurements: 6.5kg,36 x 30 x16cm Operating System: Windows 10/11Electrochemical Impedance Spectroscopy (EIS)Signal generatorFrequency range:10μHz~1MHzAC amplitude:1mV~2500mVDC Bias: -10~+10VOutput impedance:50ΩWaveform: 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 settingTechniques- CS235MStable polarizationOpen Circuit Potential (OCP)Potentiostatic (I-T curve)GalvanostaticPotentiodynamic (Tafel plot)Galvanodynamic (DGP)Transient PolarizationMulti Potential StepsMulti Current StepsPotential Stair-Step (VSTEP)Galvanic Stair-Step (ISTEP)Chrono MethodChronopotentiometry (CP)Chronoamperametry (CA)Chronocaulometry (CC)VoltammetryLinear Sweep Voltammetry (LSV)Cylic Voltammetry (CV)Staircase Voltammetry (SCV)Square Wave Voltammetry (SWV)Differential Pulse Voltammetry (DPV)Normal Pulse Voltammetry (NPV)#Differential Normal Pulse Voltammetry (DNPV)AC Voltammetry (ACV)2nd harmonic AC Voltammetry (SHACV)Fourier Transform AC Voltammetry (FTACV)Electrochemical Impedance Spectroscopy (EIS)Potentiostatic EIS (Nyquist, Bode)Galvanostatic EISPotentiostatic EIS (Optional freq.)Galvanostatic EIS(Optional freq.)Mott-SchottkyPotentiostatic EIS vs. Time (Single freq.)Galvanostatic EIS vs. Time (Single freq.)Corrosion MeasurementsCyclic polarization curve (CPP)Linear polarization curve (LPR)Electrochemical Potentiokinetic Reactivation (EPR)Electrochemical Noise (EN)Zero resistance Ammeter (ZRA)Battery testBattery Charge and DischargeGalvanostatic Charge and Discharge (GCD)Potentiostatic Charging and Discharging (PCD)Potentiostatic Intermittent Titration Technique (PITT)Galvanostatic Intermittent Titration Technique (GITT)BipotentiostatHydrogen Diffusion Test (HDT)Rotating Ring Disk Electrode(RRDE)Faradaic efficiencyTest(FE)AmperometricDifferential Pulse Amperometry (DPA)Double Differential Pulse Amperometry (DDPA)Triple Pulse Amperometry (TPA)Integrated Pulse Amperometric Detection (IPAD)Stripping VoltammetryPotentiostatic StrippingLinear StrippingStaircase StrippingSquare Wave StrippingDifferential Pulse Voltammetry StrippingNormal Pulse Voltammetry StrippingDifferential Normal Pulse Voltammetry Stripping ApplicationsCorrosion Electrochemistry CS potentiostats/galvanostats support a variety of electrochemical techniques for corrosion, such as OCP recorder, potentiodynamic, EIS, cyclic polarization (CPP), LPR, hydrogen diffusion test, zero resistance ammeter (ZRA), electrochemical noise (ECN), etc. Due to their high input impedance(1013Ω), they are especially suitable for EIS measurement of high-impedance systems like coating, concrete, and pure water.High-impedance coating ageing test in salt spray testsPolarization curves of Ti-alloy& stainless steel in 3%NaCl solutionECN of low-carbon steel in 0.05mol/L Cl+0.1mol/L NaHCO3Energy & Battery TestingWith versatile functions like linear sweep voltammetry (LSV), cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), EIS(including potentiostatic and galvanostatic modes) with precise IR compensation, CS potentiostats are widely used in supercapacitor, Li-ion batteries, Li-S batteries, fuel cell, solar cell, solid-state batteries, flow batteries, and metal-air batteries, etc. CV of PPy supercapacitor in 0.5 mol/L H2SO4 solutionElectrocatalysisBased on CV and LSV techniques, CS potentiostats can carry out long-term tests for ORR, OER, HER, and CO2 reduction, which is crucial for evaluating catalyst stability.
