srs EC301-±30 V compliance voltage, ±1A maximum current

 

主要指标与说明The EC301 gives electrochemists the opportunity to equip their labs with high compliance, research-grade instrumentation at a very attractive price. Stand-alone front-panel operation allows easy use in the field or in handling routine electrode preparation. The free Windows software (SRSLab) has routines for all major electrochemical experiments and can be downloaded from the SRS web site. The EC301 has an open command set which allows scientists to write their own unique waveforms and even write custom software.

Stand-alone front-panel operation allows easy use in the field or in handling routine electrode preparation. The free Windows software (SRSLab) has routines for all major electrochemical experiments and can be downloaded from the SRS web site. The EC301 has an open command set which allows scientists to write their own unique waveforms and even write custom software.Front-Panel OperationThe intuitive front panel of the EC301 allows you to quickly and easily set up several scan types (CV, LSV, steps and holds). Unlike many competitive models, the EC301 is a stand-alone instrument – you don’t need to use a computer. The array of indicator LEDs make it easy to know the state of the instrument at a glance.Software IncludedCyclic Voltammetry (CV) - Iron ChlorideThe SRSLab software supports all the major electrochemical techniques including voltammetry, pulsed waveforms, step techniques, and EIS. You can even design your own custom measurements. Data is acquired over the TCP/IP interface or via IEEE-488 (GPIB). The software lets you easily configure sequences of experiments and shows you the data as they are generated. The data is easily exported to spreadsheets and graphing packages.Designed for EISThe EC301 was designed with electrochemical impedance spectroscopy (EIS) in mind. Instead of employing driven shields, we bring the measurement close to the cell. This means higher accuracy and less susceptibility to parasitic effects. Shunt resistor current measurements in all ranges enhance control loop stability, enabling EIS at high frequencies.EC301 Potentiostat with option SR780EC FRAThe optionalSR780EC Frequency Response Analyzer is needed for EIS measurements. Specifications can be found in the "Specifications " tab above. The SR780EC is a full-featured FFT analyzer (identical to the SRS model SR780) that is being offered to EC301 customers at a highly reduced cost.

 

Compliance LimitingQuite often, electrochemists are working with sensitive cells which would be destroyed if the full compliance of a potentiostat were brought to bear. Bubbles in a flow cell system can easily cause potentiostats to lose voltage control by blocking feedback to the instrument from the reference electrode. Without compliance limiting, a carefully prepared electrode will be ruined. With this feature, the user can simply select the maximum potential the counter electrode will be allowed to apply. When the limit is reached, it is clamped to the preset level. Compliance limiting guarantees safe operation even if control is lost.Floating Working ElectrodeIn normal operation, the working electrode current return path is tied to chassis ground. However, there are times in which electrochemists wish to experiment with working electrodes that are intrinsically grounded (e.g., water pipes, rebar in concrete, an autoclave). Once the shorting bar from the rear panel of the instrument is removed, the ground return path floats, allowing these experiments.Fast Cyclic VoltammetryThe EC301 supports scan rates up to 10 kV/s. Potential, current and an auxiliary signal are all acquired simultaneously at 250,000 samples per second. Furthermore, an AC line detection circuit allows synchronization of repetitive scans with the power line cycle.Built-in Temperature MeasurementTemperature is a critical parameter in many battery, fuel cell and corrosion experiments, but it is often not recorded. Not knowing the temperature at which the data were acquired can make it difficult to compare your results. With a built-in input for a 100 ? platinum RTD, the EC301 makes it easy to acquire and plot temperature right along with the rest of your data.Open Command SetWhile our software supports all major electrochemical techniques, we realize that electrochemistry isn’t static. When a new technique or procedure is developed, the open command set lets experimentalists write customized software to support it. You can write in LabVIEW, MATLAB, or any other language.EC301 Potentiostat / Galvanostat SpecificationsPower Amplifier (CE)Compliance voltage ±30 VMaximum current ±1 ABandwidth >1 MHz (10 k? load, <100 μA)Slew rate ≥10 V/μsCE limit Limits counter electrode voltage when enabled Set range ±500 mV to ±30 V Bandwidth 1 MHzBandwidth limit 10 Hz, 100 Hz, 1 kHz, 10 kHz, 100 kHz, 1 MHz cutoff frequenciesDifferential Electrometer (EC19 Module)Input range ±15 VInput impedance >1 T? in parallel with 20 pFInput bias current <20 pABandwidth >10 MHzCMRR >80 dB (<10 kHz)Potentiostat ModeApplied voltage range ±15 VApplied voltage resolution 500 μV (200 μV performing an automatic scan)Applied voltage accuracy ±1 % of setting ±5 mVAutomatic scan rate 0.1 mV/s to 10 kV/sNoise and ripple <20 μVrms (1 Hz to 10 kHz)Galvanostat ModeApplied current ranges ±1 nA to ±1 A in decadesApplied current resolution 16-bitApplied current accuracy 1 A range ±0.5 % of reading ±0.2% of range All other I-ranges ±0.2 % of reading ±0.2% of rangeAutomatic scan rate 1 pA/s to 2 A/sZRA ModeVoltage offset CESense and WE electrodes held within ±5 mV of each otherVoltage MeasurementRange ±15 VResolution 16-bitAccuracy ±0.2 % of reading ±5 mVAcquisition rate 4 μs (250 kS/s)Current MeasurementRange ±1 nA to ±1 A in decadesResolution 16-bitAccuracy 1 A range ±0.5 % of reading ±0.2% of range All other current ranges ±0.2 % of reading ±0.2% of rangeAcquisition rate 4 μs (250 kS/s)
