Abstract
Die derzeitig bei chemischen Mikroanalysesystemen erkennbaren Probleme bezüglich Membranpumpen und mikromechanischer Ventile werden bei der Konstruktion des erfindungsgemäßen Mikroanalysators dadurch gelöst, daß zur Bewältigung des Fluidhandlings ausschließlich Mikrofluidmanipulatoren, das sind Mikrotropfen-Emitter und Mikro-Fluiddioden, eingesetzt sind, welche mittels mikrotechnischer Verfahren und mikrosystemtechnischer Aufbau- und Verbindungstechniken herstellbar und als modulare Komponenten flexibel koppelbar an Mikrofluidiksystem und Mikrosensoren zum Systemaufbau sind. Der erfindungsgemäße Mikroanalysator mit einem neu konzipierten Fluid-Handlingsystem zeichnet sich in besonderer Weise durch eine absolute Leckfreiheit, eine einfache Konstruktion, einen geringen Platzbedarf und eine kostengünstige Herstellung aus.
