Virtual Instrument for an Automated Potentiometric e-Tongue Employing the SIA Technique

Abstract

In this work we report the design, construction, and applications of an electronictongue (abbreviated e-tongue) based on an array of potentiometric sensors employing theSequential Injection Analysis technique (SIA) operated as a Virtual Instrument implementedin LabVIEW6.1TM. The system can use transient and stationary responses as the measuredinput information for e-tongues. The new concepts applied, lead to different advantages tobe obtained, such as complete automation, easy handling, saving time, reliability andmodularity.
