Method, device and computer-readable memory containing a computer program for determining at least one property of a test emulsion and/or test suspension

A device for determining at least one property of a test foam as a test substance, the test substance being selected from the group consisting of a test emulsion, a test suspension and a test foam, and wherein the property influences a dielectric constant of the test substance, the property being selected from the group consisting of a volume ratio between disperse and continuous phases, a drop size distribution, an average size of foam bubbles or pores and viscosity of the test substance, comprising at least one measuring device for establishing parts of the dielectric constant of the test substance at a plurality of frequencies and an evaluation device that determines the at least the test substance by using the established parts.

A computer-readable storage medium having a computer program stored thereon for determining at least one property of a test substance, the test substance being selected from the group consisting of a test emulsion, a test suspension and a test foam, and wherein the property influences a dielectric constant of the test substance and is selected from the group consisting of a volume ratio between disperse and continuous phases, a drop size distribution, an average size of foam bubbles or pores and viscosity of the test substance, the computer-readable storage medium has program parts for recording the parts of the dielectric constant of the test substance at a plurality of frequencies and for determining the at least one property of the test substance by using the established parts.

A method for determining at least one property of a test substance selected from the group consisting of a test emulsion, a test suspension and a test foam, wherein the property influences a dielectric constant of the test substance and is comprising the steps of:

• preparing a test substance to be studied;
• establishing at least one of the real and imaginary part(s) of the dielectric constant of the test substance at a plurality of frequencies;
• and determining the at least one property of the test substance by using the at least one established real and imaginary part(s), wherein the property of the test substance is determined with the assistance of at least one real and/or imaginary part of the dielectric constant of at least one reference emulsion and of at least one reference suspension and of at least one reference foam as at least one reference substance, in which the at least one property to be determined is known, and wherein the test substance property to be determined is the volume ratio between disperse and continuous phases, the drop size distribution of the disperse phase, the average drop size of the disperse phase, the average size of the foam bubbles or pores and the viscosity of the test substance.

A device for determining at least one property of a test substance selected from the group consisting of a test emulsion, a test suspension and a test foam, wherein the property influences a dielectric constant of the test substance and is different than the dielectric constant, the device comprising at least one measuring device for establishing at least one of the real and imaginary part(s) of the dielectric constant of the test substance at a plurality of frequencies and an evaluation device that determines the at least one property of the test substance by using the established real and imaginary part(s), wherein the evaluation device determines the at least one property of the test substance with the assistance of at least one real and imaginary part of the dielectric constant of at least one reference emulsion and of at least one reference suspension and of at least one reference foam as at least one reference substance, in which the at least one property to be determined is known, and wherein the test substance property to be determined is selected from the group consisting of the volume ratio between disperse and continuous phases, the drop size distribution of the disperse phase, the average drop size of the disperse phase, the average size of the foam bubbles or pores and the viscosity of the test substance.
