Abstract: Evaluation of emulsifiers comprises preparing at least two crude emulsions in which the dispersed phase contains different tracers, mixing together equal parts of the emulsions, finely emulsifying the mixture, and determining to proportion of coalesced dispersed-phase droplets by measuring the area occupied by droplets containing at least two tracers as a percentage of the total area occupied by the sample. Independent claims are also included for: (1) use of a continuous high-pressure homogenizer in which the whole emulsion is forced through a perforated diaphragm under constant pressure to perform the emulsification in the above method; (2) use of reactive dyes, direct dyes, vat dyes, sulfur dyes, naphthols, developer dyes, disperse dyes, metal complex dyes, acid dyes, chrome dyes, cationic dyes or pigments, fluorescent dyes or fluorescence-generating donor-acceptor pairs as tracers in the above method; (3) use of emulsifiers selected from oleic acid ethoxylates, fatty alcohol ethoxylates, castor oil ethyoxylates, alkylphenol ethoxylates, C13 Oxo alcohol ethoxylates and sodium fatty alcohol polyglycol ether sulfates in the above method; (4) use of emulsifiers together with coemulsifiers in the above method; (5) use of active ingredients and/or additives in the aqueous phase and/or oil phase of the emulsion in the above method; (6) use of a microscope slide allowing preparation of emulsion films with a defined thickness of 10-50 mum for microscopic determination of the area percent of tracer-containing droplets in the above method.

Abstract: The method involves isolated dosing of particles, and arranging the particles in a longitudinal axis. The supply of the particles is automated along a line. The arranged particles are observed from observation directions (1.1,1.2,1.3) and image capture. The images are evaluated. The dosing of particles of the sample takes place with the help of dosing channels in particular two dosing channels, which are connected one behind the other. The particle axis is aligned along the line transverse to the observation direction. Independent claims are also included for the following: (1) a method for reconstruction of volume of individual particles (2) a method for determining surface of the individual particles (3) a device for automated determination of individual, three dimensional form of particles of samples.

Abstract: In making systems of the finest particles, to determine their size and/or shape, a microscopic method is employed, especially an optical method based on electron- or light microscopy. An Independent claim is included for the corresponding particulate system. Preferred Features: The finest particles are dispersed and diluted. The dispersion is atomized, in such a way that particles are separated onto a substrate for microscopy or electron microscopy. Here they form differentiable units. Atomization is by air-brush. In an additional stage of the process, an additive is introduced.
