20090026373 | System for Producing and Checking Tablets - 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. | 01-29-2009 |
20080285013 | Method of Checking the Filling Volume of Blisters - A method for checking the volume of material in the form of a thin layer of a powdery substance in pockets of a blister pack including: bringing at least one blister pack to the measuring area of a measuring system, the pack including a plurality of pockets which are designed to be reflective and are filled with a thin layer of the substance; exposing the substance in at least one of the pockets to near-infrared radiation; recording at least partial ranges of an actual reflectance spectrum for each pocket by detecting the radiation reflected from the pocket; calculating actual values associated with the intensities displayed in the actual reflectance spectrum for at least partial ranges of the actual reflectance spectrum; comparing, in at least partial ranges of the actual reflectance spectrum, the calculated actual values with corresponding reference values associated with the intensities displayed in at least one model spectrum; and checking the ratio of the layer thickness to the density of the powdery substance as a function of the result of the comparison. | 11-20-2008 |
20080230700 | METHOD AND DEVICE FOR THE QUANTITATIVE ANALYSIS OF SOLUTIONS AND DISPERSIONS BY MEANS OF NEAR INFRARED SPECTROSCOPY - 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. | 09-25-2008 |
