Title: MOBILE VOLTAMMETRIC ANALYSIS
Abstract:
A low-cost voltammetric analysis system using a mobile computing device (300) having a microprocessor (320), a memory (324) and an audio interface (332, 334). The audio interface comprises an audio signal output (332) having first and second channels and an audio signal input (334). The interface is connectible to a voltammetric cell (102) comprising first and second electrodes (104, 106), and the memory of the device contains instructions (336) which, when executed by the microprocessor, cause the device to: generate an output voltage waveform (310, 312) between the first and second channels of the audio signal output, the output voltage waveform comprising a time-varying voltammetric driving potential and an AC perturbation; simultaneously with generating the output voltage waveform, capture an input voltage waveform (314) received at the audio signal input; and record (420) the input voltage waveform as a voltammetric response waveform (314) within a data store (324).
