System and method for the spectroscopic determination of the components and concentrations of pumpable organic compounds

摘要

The present invention is directed to a fast, nondestructive measurement method for determining the contents of solid, liquid and/or suspended flowing organic compounds. The arrangement according to the invention comprises a sample vessel, a pump, and a measurement cell which form a unit together with a spectroscopic measurement head. The measurement cell is connected to the pump, which can be regulated to vary the flow rate, and to the sample vessel by a pipe, and the spectroscopic measurement head and the regulatable pump have electrical connections to a controlling and evaluating unit. Due to its compact construction, the solution which makes use of the principle of transflection is also particularly suited to mobile use, for example, to determine the components of liquid manure while the latter is being dispensed. In principle, the solution can be transferred to any applications with suspensions or pumpable, homogeneous and inhomogeneous materials.

1. An arrangement for spectroscopic determination of components and concentrations of any pumpable material, comprising:
a sample vessel; a pump; and a measurement cell with a spectroscopic measurement head which carries out a nondestructive spectroscopic measurement of a sample of the pumpable material by light absorption and/or light transmission; wherein said measurement cell is connected to the pump, which can vary the flow rate, and to the sample vessel by a pipe; wherein said spectroscopic measurement head and the regulatable pump havehas electrical connections to a controlling and evaluating unit; wherein the through-flow volume of an outlet valve provided in the outlet line of the vessel is regulated by the controlling and evaluating unit; and wherein the controlling and evaluating unit determines components and concentrations of substances contained in the sample, and regulates the through-flow of the outlet valve based on the determined components and concentrations of the substances contained in the sample.
