A three-dimensional flow cell for aligning non-isometric particles in a liquid sample in two axes, a method of aligning non-isometric particles in a liquid sample, the use of the three-dimensional flow cell, a reflectance sensor which has the three-dimensional flow cell according to the invention, a method of measuring the reflectance of a liquid sample containing non-isometric particles and the use of the reflectance sensor according to the invention.

Precise flow-oriented multi-angle remission sensor

The invention relates to reflectance sensors built up from an optical unit, a sample analysis unit and a system control unit, and to a method of measuring the reflectance of a sample in the form of a liquid pigment preparation, and to the use of a reflectance sensor according to the invention for the measurement of the reflectance of liquid pigment preparations in various process stages during the production, further processing and use of the liquid pigment preparations.

Reflectance sensor for measuring liquid pigment preparations or solid pigmented surfaces

In a method for monitoring of polymer in a liquid state, such as a polymer melt or resin, to detect inhomogeneities therein, such as the presence of other phase objects, especially gels in a matrix formed of the liquid state, the polymer in a liquid state flowing past an inspection point is monitored. At the inspection point, electromagnetic radiation in the form of UV light or polarised electromagnetic radiation is passed through the flow chamber () and received by a detector (), and the absorption of the UV light or the changes in the state of polarisation of the electromagnetic radiation caused by the inhomogeneities are used to observe them.

Method for monitoring of polymer in liquid state

In a proposed method for determining the immobilization of a colloidal coating dispersion which is applied to a porous substrate, the colloidal coating dispersion is applied to the porous substrate which forms a bounding surface of the measuring gap of a rheometer, and the change in the viscosity as a function of time is measured. The method is particularly suitable for measuring the immobilization of a paper coating slip on base paper.

Determination of the immobilization of colloidal coating dispersions

A method for the continuous colorimetry of plastics molding compounds, which involves light being introduced, via transmitter light pipes and a sensor head, into the melt of the molding compound and the light reflected there being passed, via receiver light pipes, to a spectrometer or multirange photometer, conjugate transmitter and receiver light pipes in each case being spaced equidistantly.
