Virtual instrumentation forelectro–analytical measurements

[摘要] This paper deals with some applications of Virtual Instrumentationto electroanalytical measurements. Virtual Instruments (VIs)are software programmes that simulate the external appearanceand functions of a real instrument on the screen of a computer. Inthis work, programmes have been developed to control the potentialof a working electrode (through a suitable potentiostat), acquirethe current response, process the acquired current signal, andcontrol a peristaltic pump and injection valve. The sequence ofoperations was controlled by the VI. The programmes developedhave been applied to amperometric and voltammetric measurementsin static and flowing solutions. The Vl package that has been usedwas Lab VIEW 4.0.1 from National Instruments.
