|
|
OpenVoltam
|
Software used for data acquisition, peak analysis, and concentration calculation.
|
|
Rodeostat
|
Low-cost open hardware potentiostat used to run electrochemical measurements.

|
Working electrode
|
Electrode where arsenic is deposited and measured; gold microwire in this method.
|
|
Reference electrode
|
Electrode that provides a stable reference potential; Ag/AgCl in this method.
|
|
Counter electrode
|
Electrode that completes the electrical circuit.

|
Voltammogram
|
Plot of current versus applied potential.
|
|
Peak height
|
Measured arsenic signal used for quantification.

|
LOD
|
Limit of detection; lowest concentration reliably distinguishable from background noise.
|
|
Linear range
|
Concentration range where signal increases proportionally with concentration.
