Abstract

Die Erfindung betrifft ein Titrationsverfahren für kleinste Flüssigkeitsmengen, bei dem ein durch seine Oberflächenspannung zusammengehaltener Tropfen (1) eines Analyten auf die im wesentlichen ebene Oberfläche (7) eines Festkörpers, vorzugsweise eines Festkörperchips, aufgebracht wird, eine Menge (17) des Titranten mit dem Analyttropfen (1) zur Reaktion in Kontakt gebracht wird, die kleiner ist als die Menge des Analyttropfens, und eine für die Reaktion zwischen Titrant und Analyt charakteristische Grösse während und/oder nach der Reaktion gemessen wird.
