Patent number: 7755051Abstract: The present invention relates to a method for quantifying the composition of a product, including: irradiating the product with a radiation source in the near infrared range; receiving radiation which is reflected by or transmitted through the product; providing an output signal corresponding to the intensity of the radiation received at a number of different wavelengths; and determining whether or not the product lies within predetermined integrity criteria on the basis of the output signal using a mathematical method. The moving product contains a solution or homogeneous dispersion and the content of at least one substance contained in the dispersion or solution is quantitatively determined on the basis of the output signal. The invention also relates to a device for carrying out this method.Type: GrantFiled: June 14, 2007Date of Patent: July 13, 2010Assignees: Sanofi-Aventis Deutschland GmbH, Uhlmann Visiotec GmbHInventors: Christian-Peter Christiansen, Hans-Joachim Ploss, Richard Mertens, Heino Prinz

Publication number: 20090026373Abstract: A system for inspecting tablets includes an NIR measuring device for determining the concentration of at least one active ingredient in the tablets. The system also includes a sensor for determining the volume of the individual tablet, and a control unit which is able to calculate the actual active ingredient dose of the tablet under consideration of the data acquired by the NIR measuring device and the volume-determination sensor. A corresponding method of inspecting tablets is also described.Type: ApplicationFiled: July 18, 2008Publication date: January 29, 2009Applicant: UHLMANN VISIOTEC GMBHInventors: Richard Mertens, Heino Prinz
