Abstract
Description
Die Erfindung betrifft eine Anordnung zur Bestimmung von Fett und Eiweiß in biologischen Materialien, insbesondere in Milch.The invention relates to an arrangement for determining fat and Protein in biological materials, especially milk.
Bestimmungen von Fett und Eiweiß in biologischen Materialien er folgen bekanntermaßen im nahen und mittleren Infrarot. Für die Analysen erfolgt eine spektrale Zerlegung des Meßlichtes vorzugs weise mit Interferenzfiltern. Jede auf diese Weise ausgewählte Wellenlänge wird auf einen Empfänger gerichtet und nachfolgend ausgewertet.Determination of fat and protein in biological materials are known to follow in the near and mid-infrared. For the Analysis is preferably a spectral decomposition of the measuring light wise with interference filters. Each selected this way Wavelength is aimed at a receiver and subsequently evaluated.
Der Nachteil derartiger Anordnungen liegt in der nicht sehr hohen zeitlichen Beständigkeit der Interferenzfilter und im hohen mechanischen Aufwand zum Bewegen der Filter. Von Nachteil ist es außerdem, die interessierenden Wellenlängen nacheinander messen zu müssen, was einen erheblichen Zeitaufwand erfordert. The disadvantage of such arrangements is that they are not very high temporal stability of the interference filter and in the high mechanical effort to move the filter. Another disadvantage is the wavelengths of interest having to measure one after the other, which takes a considerable amount of time required.
Die Aufgabe der Erfindung besteht darin, eine mit einer Verlage rung des Meßbereiches in den ultravioletten Spektralbereich ver bundene Verknüpfung von flexibler, gleichzeitiger oder quasi gleichzeitiger Wellenlängenauswahl und Zeit- und Kosteneinsparung zur Bestimmung des Fett- und Eiweißgehaltes, insbesondere in Milchproben, zu gewährleisten. Mechanische Wechseleinrichtungen sollen dabei vermieden werden.The object of the invention is one with a publisher tion of the measuring range in the ultraviolet spectral range bound link of flexible, simultaneous or quasi simultaneous wavelength selection and time and cost savings to determine the fat and protein content, especially in Milk samples to ensure. Mechanical changing devices should be avoided.
Erfindungsgemäß wird die Aufgabe durch eine Anordnung zur Bestim mung von Fett und Eiweiß in biologischen Materialien, insbesondere Milch gelöst, bei der Strahlung einer im wesentlichen im ultra violetten Bereich emittierenden Strahlungsquelle auf eine mit dem zu analysierenden biologischen Material gefüllte Küvette gerichtet ist, indem im Strahlengang zwischen der Strahlungsquelle und der Küvette ein Verschlußelement vorgesehen ist, mit dem eine Strah lungsfreigabe nur während einer Messung erfolgt, für die an Orten zur Bestimmung von Fett und Eiweiß notwendiger Wellenlängen mit einer Auswerteelektronik gekoppelte Empfänger angeordnet sind, wobei die Orte durch ein feststehendes, abbildendes Gitter einer Polychromatoranordnung festgelegt sind.According to the invention, the object is determined by an arrangement Fat and protein in biological materials, in particular Milk dissolved in the radiation of an essentially ultra radiation source emitting on a violet area with the filled cuvette to be analyzed biological material is by in the beam path between the radiation source and the Cuvette a closure element is provided with which a beam Release only takes place during a measurement, for those at locations for the determination of fat and protein of necessary wavelengths coupled to an evaluation electronics are arranged, where the locations are defined by a fixed, imaging grid Polychromator arrangement are set.
Die Erfindung soll nachstehend anhand der schematischen Zeichnung näher erläutert werden.The invention is based on the schematic drawing are explained in more detail.
Die Figur zeigt eine optische Anordnung zur Fett- und Eiweißbe stimmung, bei der entlang eines Strahlenganges 0-0 nacheinander eine im wesentlichen im ultravioletten Bereich emittierende Strahlungsquelle 1, eine Optik 2, ein Verschluß 3 und eine Küvette 4 angeordnet sind. Zur Spektralzerlegung der durch die Küvette 4 während eines Meß vorganges hindurchtretenden Strahlung dient ein Polychromator, bestehend aus einem Eintrittsspalt 5, dem eine Optik 6 vorgeordnet ist, und ein abbildendes, speziell für den ultravioletten Bereich ausgebildetes Konkavgitter 7. Eine in der Fokalebene des Poly chromators vorgesehene Empfängeranordnung 8, die mit einer Aus werteelektronik 9 gekoppelt ist, besitzt Empfänger an Orten, die für die Bestimmung von Fett und Eiweiß relevant sind. Als Empfänger sind bekanntermaßen eine Photodioden- oder CCD-Zeilenanordnung geeignet.The figure shows an optical arrangement for fat and protein determination, in which a radiation source 1 , optics 2 , a closure 3 and a cuvette 4 are arranged one after the other along a beam path 0-0 in succession, essentially in the ultraviolet range. A polychromator, consisting of an entrance slit 5 , which is preceded by an optical system 6 , and an imaging concave grating 7 , which is specially designed for the ultraviolet range, is used for spectral decomposition of the radiation passing through the cuvette 4 during a measurement process. A provided in the focal plane of the poly chromator receiver arrangement 8 , which is coupled to an evaluation electronics 9 , has receivers at locations that are relevant for the determination of fat and protein. As is known, a photodiode or CCD line arrangement is suitable as a receiver.
Da durch die Arbeit im ultravioletten Bereich eine Veränderung des zu analysierenden Materials erfolgen kann, ist der Strahlungs durchtritt durch die Küvette 4 außerhalb der Meßzeit mit dem Verschluß 3 unterbrochen. Die in elektrische Signale umgewandelten optischen Signale bilden die Grundlage für die im wesentlichen gleichzeitige Analyse aller interessierenden Meßgrößen.Since a change in the material to be analyzed can occur due to the work in the ultraviolet range, the radiation passage through the cuvette 4 is interrupted with the closure 3 outside the measuring time. The optical signals converted into electrical signals form the basis for the essentially simultaneous analysis of all measured variables of interest.
