Abstract:
The invention relates to a method of controlling a product analysis spectrometer, the method comprising steps consisting in: acquiring a measurement (LFL, TPL) representative of the operation of a light source (LS), determining as a function of the measurement a value of supply current (LCx) of the light source, and/or a value of duration of integration (ITy) of photosensitive cells (y) of a sensor (OPS), which are disposed on a path of a light beam (LB) emitted by the light source and having interacted with a product to be analyzed, and if the value of duration of integration and/or of supply current lies between threshold values, providing to the light source a supply current corresponding to the determined value of supply current, adjusting the duration of integration of a photosensitive cell to the determined value of duration of integration, and acquiring measurements of luminous intensity (MSy) which are provided by the sensor, making it possible to form a spectrum.
Abstract:
A method of normalizing an analyzer response value of a fluorescence analyzer is provided. The method includes measuring an excitation spectrum of the analyzer and measuring an emission sensitivity spectrum of the analyzer. Next, a normalization factor based at least in part upon the excitation spectrum of the analyzer and the emission sensitivity spectrum of the analyzer is determined. The sample is then analyzed to obtain an uncorrected analyzer response value. A normalized analyzer response value is calculated based at least in part upon the uncorrected analyzer response value and the normalization factor.

Bei der Bestimmung von Meßgrößen in der analytischen Chemie, insbesondere zur Trübungsmessung in wässrigen Meßmedien, mit einem optischen Sender und einem zugeordneten Empfänger, der ein durch den Einfluß des Meßmediums verändertes (geschwächtes) Ausgangssignal zur Auswertung erzeugt, wird vorgeschlagen, das Ausgangssignal des optischen Empfängers, üblicherweise eine Empfangsdiode, unterschiedlichen Verstärkungsgraden zu unterwerfen und die gewonnenen Signale mit unterschiedlichem Signalpegel jeweils separat einer logischen Auswerteschaltung, vorzugsweise einem Mikroprozessor, zuzuführen, der nach Bewertung der Signalabstufungen eine Meßwertanzeige durchführt.
Abstract:
The present invention relates to a method for monitoring the filling of a capsule with a medicament, to a corresponding filling method, to the associated apparatuses, and to a computer program for controlling the method and the apparatus. In the monitoring method, after at least part of the capsule has been filled with a predefined filling mass of a predefined closed contour of the medicament, at least the filling mass in the part of the capsule after the filling operation is recorded using digital imaging in a first step, the contour of the filling mass in the part of the capsule is determined from the digital imaging recording in a second step, and the contour is analysed in a third step in order to assess the filling operation in comparison with the predefined contour. The invention provides for external influences on the image properties to be compensated for by controlling the optical system.
