app family

Electrochemistry Apps

The Electrochemistry family reads Gamry DTA files through labkit.dta and keeps experiment-specific analysis, plotting, defaults, and export schemas in the owning app. Source DTA files are never modified.

Choose An App

Measurement or task	App	Required DTA content	Main result
Compare voltage and current transients across files	Chrono Overlay	chrono curve with `T`, `Vf`, `Im`	aligned overlay and wide CSV
Charge-injection capacity and polarization voltage	CIC	biphasic chrono transient	per-file CIC, charge, and voltage metrics
Charge-storage capacity by time and CV integration	CSC	CV/CT cycles with `T`, `Vf`, `Im`	per-cycle CT/CV CSC comparison
Impedance inspection and export	EIS	`ZCURVE`	configurable Nyquist/Bode-style overlay
Steady pulse resistance	VT Resistance	biphasic chrono transient	cathodic, anodic, and mean resistance

Shared File Behavior

File controls accept one or more .DTA files from one folder in a single selection. A canceled chooser leaves the current project unchanged. CIC, CSC, and VT Resistance use the selected row as the active preview while retaining the loaded source list for batch export. Invalid items are reported per file; one failed item does not silently replace another result.

The DTA library returns structured items, curve tables, headers, units, metadata, parser messages, and status. Apps use exact required columns for scientific calculations and do not infer missing physical quantities from a plot label.

Units And Traceability

Time is seconds, voltage is volts, current is amperes, impedance is ohms, charge is coulombs, electrode area is square centimetres, and normalized CIC or CSC is reported in the unit shown by the app. UI display conversions do not change stored base-unit calculations.

Export tables include the source identity and analysis settings needed to interpret the result. Runtime-generated .labkit.json files are provenance manifests describing inputs, parameters, and output roles; they are not a second numerical result and can be kept with the corresponding CSV.

Use Without The GUI

Reusable parsing and curve access live in labkit.dta. App-specific numeric operations such as cic.analysisRun.computeCIC, csc.analysisRun.computeCSC, and vt_resistance.analysisRun.computeResistance are documented on the owning app page and in the generated API reference.
