The invention relates to a process for producing a sensitive single-layer system for the optical determination of a concentration of an analyte, e.g. oxygen, in which the analyte can be examined in a liquid or gaseous aggregate state or in solution, by absorption, luminescence or luninescence washing of an indicator sensitive to the analyte which is preferably permanently immobilised in the optical beam path. The sensitive single-layer system is designed thereby to have a reproducible and very short response. To this end indicators are adsorbed on a filler, whereafter a mixture is made with a matrix material permeable to the analyte to be determined. The mixture is then applied under pressure to a substrate and the layer thickness is determined by the pressure applied. The sensitive layer applied is polymerised, polycondensed or cured and also homogenised by soaking in a fluorescence indicator solution.

L'invention concerne un procédé de réalisation d'un système monocouche sensible pour déterminer de manière optique une concentration d'analyte, telle que l'oxygène, l'analyte étant analysé sous forme d'agrégat liquide ou gazeux ou sous forme de solution, par absorption, luminescence ou lavage par luminescence d'un indicateur sensible à l'analyte, immobilisé de manière permanente de préférence dans la trajectoire du faisceau. Le système monocouche sensible doit de ce fait pouvoir atteindre un mode de réponse très court et reproductible. A cet effet, des indicateurs sont adsorbés sur une charge, puis un mélange est ensuite produit avec un matériau matriciel perméable à l'analyte à déterminer. Le mélange est ensuite appliqué par pression sur un substrat, l'épaisseur de la couche obtenue dépendant de la force de la pression appliquée. La couche sensible appliquée est alors polymérisée, polycondensée ou durcie, et également homogénéisée par gonflement dans une solution d'indicateur fluorescent.
