Documentation
Hardware setup, Sensitify Studio, and troubleshooting. New users should start with Getting started.
Hardware
Setting up the instrument, connecting a cell, and updating firmware.
- Getting startedPower, USB connection, installing Sensitify Studio, and a first measurement on the dummy cell.
- Device quickstartWhat differs between the ECA-LP1, 5M, 500k, and Zero: power, modes, EIS bandwidth, and galvanostat availability.
- Firmware updateUpdating the firmware over USB from Studio, checking the version, and what happens if an update is interrupted.
- Cell & electrode setupCable pinout, physical connection of a three-electrode cell to your ECA, and the Sensitify fixtures for screen-printed and interdigitated electrodes.
Software
Running experiments and analysing data in Sensitify Studio.
Overview
- Studio: UI tourThe Studio window: the controls on the left (Method Setup, Parameters, Post-processing, Device), the plot in the middle, and the experiment list on the right.
- File formatsThe .stfy file, the export formats (Excel, CSV, ASCII, MATLAB, PNG, PDF), and import from other instruments.
- Appearance & shortcutsLight and dark appearance, window layout, the keyboard shortcut reference, and the recent files list.
Running experiments
- Run a CVSet up vertex potentials, scan rate, and cycles. Live plotting, saving, and exporting a cyclic voltammogram.
- Run EISFrequency range, AC amplitude, DC bias, and multi-sine mode. Nyquist and Bode views.
- Pulse voltammetry (DPV / SWV)Pulse height, pulse width, step potential, and frequency for DPV and SWV.
- AmperometryHold the working electrode at a constant potential and record the current over time. The Cottrell-style transient and the steady-state value.
- PotentiometryOpen-circuit measurement: no current flows, the instrument records the cell potential against a stable reference over time.
- ChronopotentiometryGalvanostatic technique: hold a constant current and record the potential transient as the cell responds. ECA-LP1 only.
- SequencerChaining techniques with Loop, If/Else, Sweep, Wait, and Gate blocks and running the sequence unattended.
Analysing data
- Fit a circuitPicking an equivalent circuit, running the fit, reading the residuals, excluding points, and fixing convergence failures.
- Find peaksClick the Pk badge to detect peaks on a voltammogram. What Studio finds and where the results appear.
- Integrate a peakThe charge under each peak: how Studio places the baseline and how to convert Q to coverage, efficiency, or mass.
- Data processingFiltering a curve (Savitzky-Golay, moving average, median, FIR low-pass, notch) and restricting it to a range or CV cycle. Presets, the spectrum view, and where the filtered data is used.
- Export for publicationChoosing an export format (PDF, PNG, Excel, CSV, ASCII, MATLAB, .stfy), copying to the clipboard, and keeping axis ranges consistent across figures.
- Publication WorkbenchThe multi-experiment figure builder: calibration, Randles–Ševčík, Tafel, dose-response, box plot, and bar graph modes, and the journal presets.
