Description
"Absorptionsmeßgerät" Die Erfindung bezieht sich auf ein Absorptionsmeßgerät. "Absorbance Meter" The invention relates to an absorption meter.
Absorptionsmeßgeräte sind-Geräte, bei denen ein Medium durch strahlt wird (z.B. mit infrarotem Licht oder Ultraschall) und die absorbierte Energie meßtechnisch ausgewertet wird.Absorption meters are devices in which a medium radiates through is measured (e.g. with infrared light or ultrasound) and the absorbed energy is evaluated.
Bei bekannten Geräten dieser Art ist die aktive Länge der Kammer für die zu durchstrahlende Probe und damit der Meßbereich fest.In known devices of this type, the active length of the chamber is for the sample to be irradiated and thus the measuring range.
Der Erfindung liegt die Aufgabe zugrunde, ein AbsorptionsmeS-gerät derart auszubilden, daß der Meßbereich variiert werden kann.The invention is based on the object of an absorption measuring device to be designed in such a way that the measuring range can be varied.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daB die Kammer für die zu durchstrahlende Probe hinsichtlich ihrer aktiven Länge veränderbar ist.This object is achieved according to the invention in that the chamber is variable for the sample to be irradiated with regard to its active length.
Die Erfindung wird im folgenden an Hand dreier in der Zeichnung dargestellter Ausführungsbeispiele erläutert.The invention is illustrated below with reference to three in the drawing Embodiments explained.
In allen drei Figuren ist mit 1 eine Strahlungsquelle, mit 2 ein Detektor und mit 3 eine Absorptionskammer bezeichnet.In all three figures, 1 is a radiation source, and 2 is a detector and 3 denotes an absorption chamber.
Im Falle der Fig. 1 ist die Kammer 3 teleskopartig ausgebildet.In the case of FIG. 1, the chamber 3 is designed telescopically.
Im Ralle der Fig. 2 hat die Kammer 3 eine feste Länge. Eine Trennwand 4 ist in Längsrichtung verschiebbar. Auf der einen Seite der Trennwand kann die Probe, auf der anderen Seite der Trennwand kann ein neutrales Medium eingelassen werden.In the rail of FIG. 2, the chamber 3 has a fixed length. A partition 4 is displaceable in the longitudinal direction. On one side of the partition, the Sample, a neutral medium can be admitted on the other side of the partition will.
In Fig. 3 ist eine Kammer dargestellt, die aus mehreren Räumen 5, 6, 7 und 8 besteht. Diese sind durch Wände voneinander getrennt. Bedarfsweise können gewisse Räume mit dem zu untersuchenden Medium und andere Räume mit einem neutralen Medium gefüllt werden.In Fig. 3, a chamber is shown, which consists of several rooms 5, 6, 7 and 8. These are separated from each other by walls. If necessary, can certain rooms with the medium to be examined and other rooms with a neutral one Medium to be filled.
In der erfindungsgemäßen Art und Weise kann auch eine Filterkammer bzv. eine Vergleichskammer (beide kommen bei Absorptionsgeräten zur Anwendung) ausgebildet sein.A filter chamber can also be used in the manner according to the invention bzv. a comparison chamber (both are used in absorption devices) be.
