  1. 1. Sensor Systems for Bioprocess Monitoring

    Författare :Helena Lidén; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; on-line; pattern recognition; gas sensor array; electronic nose; monosaccharides; ethanol; biosensor; carbon paste electrode; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. LÄS MER

  3. 2. Multivariate Exploration and Processing of Sensor Data-applications with multidimensional sensor systems

    Författare :Henrik Petersson; Martin Holmberg; Johan Trygg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical sensor; Pattern recognition; sensor selcection; Combustion monitoring; Vector Classification; Chemical engineering; Kemiteknik;

    Sammanfattning : A sensor is a device that transforms a physical, chemical, or biological stimulus into a readable signal. The integral part that sensors make in modern technology is considerable and many are those trying to take the development of sensor technology further. LÄS MER

  4. 3. Silicon carbide field-effect devices studied as gas sensors for exhaust gas monitoring

    Författare :Peter Tobias; Ignaz Eisele; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon carbide; high temperature; gas sensors; field effect devices; MISdevices; Schottky diodes; experimental design; reaction kinetics; mass transport; car exhaust; multipoint injection; response times; cylinder specific; on-board diagnosis;

    Sammanfattning : Metal-insulator-silicon carbide (MIS) structures have been studied as gas sensors. We have investigated how the sensors detect gases, how fast they do that, and how they could be used for exhaust gas monitoring.We have prepared simple field-effect devices, MIS-capacitors and Schottky diodes, on silicon carbide with platinum gates.

  5. 4. Spatially resolved gas sensing

    Författare :Mikael Löfdahl; Werner Moritz; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : By using a Scanning Light Pulse Technique (SLPT) the gas response of catalytic Metal-Insulator semiconductor (MIS) devices can be spatially resolved.The application of SLPT to gas sensitive MIS devices can be divided into two areas. LÄS MER

  7. 5. Methods to Improve the Selectivity of Gas Sensor Systems

    Författare :Tomas Eklöv; Corrado Di Natale; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In several situations it is essential to be able to measure the composition of a gas mixture, discriminate between or quantify different gases mixtures (odors), or in some cases to give a 'fingerprint', which represents the gas mixture. A gas sensor system is designed to measure certain attributes of a gas mixture. LÄS MER
