Lh. Mazo et al., A LOW-COST CURRENT FOLLOWER FOR VOLTAMMETRIC MEASUREMENTS WITH ULTRAMICROELECTRODES, Instrumentation science & technology, 22(1), 1994, pp. 61-72
This paper describes the development of a low cost current follower, s
uitable for current measurements in the pico to micro-ampere range in
general laboratory and field applications. The versatile instrument is
designed for voltammetric measurements with ultramicroelectrodes, in
a two-electrode cell configuration. The signal output can be monitored
either by using an analog-to-digital converter or by a conventional e
lectromechanical recorder. Performance tests in which the potential ra
mp and the signal current acquisition were performed using a digital-t
o-analog and analog to digital interface and an IBM-PC microcomputer a
re also described.
