Abstract
(A1) Die vorliegende Erfindung betrifft ein Verfahren zur Bestimmung einer in einen zu befuellenden Koerper zudosierten Menge eines fliessfaehigen Stoffes, wobei ein Terahertz-Impuls erzueugt wird, der den zu befuellenden Koerper und die darin aufgenommene zudosierte Menge des fliessfaehigen Stoffes durchlaeuft, und wobei die zudosierte Menge des fliessfaehigen Stoffes aus einer Laufzeit des Terahertz-Impulses ermittelt wird.

 

WO 2010133335 A1 UPAB: 20101208 NOVELTY - The method involves generating terahertz impulse that passes through a body to be filled and through a dosage amount of free-flowing substance received in the body. A reference measurement is carried out, where the body is produced as a reference sample during the reference measurement. A propagation delay of the terahertz impulse is determined before and after dosage of the substance into the body. The dosage quantity of the free-flowing substance is determined from a run time of the terahertz impulse and the propagation delay. USE - Method for determining mass and volume of a free-flowing substance e.g. powdered substance and liquid substance, to be microdosed into a body i.e. capsule, to be filled during production of the body (all claimed) in a production line in a pharmaceutical industry. ADVANTAGE - The method enables accurately, quickly and uniformly determining the quantity of the free-flowing substance to be microdosed into the body in a non-destructive manner.
