MDA starts from a strict two-column input: time in seconds first, measured current second. Decimal handling sits next to the paste field, and uploads use the same parser as pasted data so the tool stays predictable.
Input rules
- No header row.
- Exactly two numeric values per line.
- One sample per line.
- Dot or comma decimals are accepted, but only one style should be used in the file.
- Start the file at the actual experiment start. Do not include a long pre-equilibration segment unless you really want that time counted in the breakthrough analysis.
Controls
- Use the current unit and membrane thickness controls to keep the experimental metadata attached to the file.
- Set the baseline and steady-state values above the plot. Use the adjacent button to show or hide each marker line, and drag the marker when it is visible.
- Use Plot Options to change display units or grid visibility.
What you get
- Validation messages for obvious formatting problems.
- A preview plot with the measured current and calculated apparent diffusion coefficient.
- The normalized signal used internally for the inverse solve.
- Export for PNG, SVG, or plotted data.
Caveats
- Header rows are not allowed in this first version.
- If autodetection gets the decimal separator wrong, use the dropdown to override it.
- The tool is local-first; the file contents stay in your browser.
