• Resumen

  • There is growing interest in chemical analysis because of the social need of information in many areas. Industrial process controls, environmental monitoring, as well as product quality monitoring, are some of the points where research is immersed nowadays. One of the research lines that is getting more significance in Analytical Chemistry is the development of automatic systems of analysis because of this increasing need of information, sometimes in real time. It is already possible to determine a huge variety of analytes in a single analysis when using heavy laboratory set-ups such as gas chromatography or mass spectrometry, but their cost and maintenance is sometimes a drawback in laboratory implementation. The need of robust and cost-effective devices has pushed researchers into the development of simple systems that do not try to compete with heavy laboratory set-ups, but that are good enough to satisfy the need of information in many situations.

    In this effort of developing new analytical systems it is possible to find those systems coined under the name of electronic noses and electronic tongues. These devices are considered as biomimetic systems, as long as they are based in imitating the human senses of smell and taste. The first electronic noses appeared many years ago, but are still useful in many areas. Electronic tongues appeared some years after the electronic noses, and are still considered as one of the research topics in Analytical Chemistry.

    The development of these systems has been a compendium of efforts in many laboratories of many countries around the world.

    The present work pretends to add some useful information into the electronic tongues development, with the aim of increasing the significance of electronic tongues in the present research. The development of an automated sequential injection system has been one of the key points in our work, as long as it is known that electronic tongues need huge amount of pre
