Inventor: BRAUN ROLAND
IPC: G01N15/08
Filed: 1983-03-28
Abstract: Die Erfindung betrifft ein Verfahren zur Messung des Porenvolumens und seiner Änderung und dient der labortechnischen Untersuchung poröser und permeabler Poren. Ziel der Erfindung ist es, die Aussagefähigkeit und Anwendbarkeit derartiger Messungen zu erhöhen. Die Aufgabe der Erfindung ist es, ein Meßverfahren zu entwickeln, das die Messung des Porenvolumens und seiner Änderung unter beliebiger innerer (Porendruck) und äußerer Belastung in beliebigen Apparaturen gewährleistet. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der Porenraum eines Probekörpers evakuiert, in das evakuierte System eine Flüssigkeit gesaugt, deren Volumen gemessen, davon das Meßsystemvolumen subtrahiert wird und damit das Porenvolumen bestimmt ist und bei auftretenden Druckänderungen mit dem Kolben der Stellpumpe die Druckänderung ausgeglichen wird und damit die Porenvolumenänderung bestimmt ist.
