Abstract

The term 'integrated analytical systems' illustrates the convergence of different strategies to connect the steps of the analytical process including simplification, automation, communication and miniaturisation. Although these strategies or trends are found in other scientific and technological fields, it is with chemical sensors and sensing systems that they take on defined role producing analytical instruments with additional advantages in terms of information, speed, robustness, portability and cost (see Table I).

Keywords: Integrated analytical system; chemical sensor; electronic nose; biochip; lab–on–a–chip.

Resumen

El termino 'sistemas analíticos integrados' ilustra la convergencia de diferentes estrategias para conectar las etapas de los procesos analíticos incluyendo simplificación, automatización, comunicación y miniaturización. Aunque estas estrategias o tendencias se encuentran en otros campos científicos y tecnológicos, es con los sensores químicos y sistemas sensores que ellas toman un papel muy definido, produciendo instrumentos analíticos con ventajas adicionales en términos de información, velocidad, robustez, portabilidad y costo (ver Tabla I).

Descriptores: Sistema analítico integrado; sensor químico; microsistema analítico; nariz electrónica; biochip; laboratorio en un chip.
