The present invention relates to a method of and a device for optimizing at least one coating material at at least one point of a substrate surface to which the coating material is applied. The method, which is carried out with the corresponding device, comprises at least the following steps: a) applying said at least one coating material to said at least one point of the substrate surface, b) curing said at least one coating material at said at least one point of the substrate surface, and c) determining the state, especially the curing and/or yellowing and/or gloss, of said coating material at said at least one point of the substrate surface, possessed by said coating material as a consequence of steps a) and b).

Method for optimizing lacquers

The invention relates to a process and an apparatus for producing stably fine-particle powders. The invention starts from a process for producing stably fine-particle powders in which one or more substances A and one or more substances B are dissolved in supercritical fluids, and the solutions are decompressed along a holdup section. In the process, substances A and B are each dissolved in separate supercritical compressible fluids, and the holdup sections interpenetrate, with the solubility limit of A in the appropriate fluid being exceeded at an earlier time than is the solubility limit of B in the appropriate fluid.

The use of solubilized carotenoid preparations is described for coloring foods, wherein solubilized carotenoid preparations are used which are produced by heating a suspension comprising from 1 to 40% by weight of one or more carotenoids, from 20 to 90% by weight of one or more nonionogenic emulsifiers and from 0 to 50% by weight of other additives to from 120 to 200&deg; C. for a short time and turbulently mixing the homogeneous solution with amounts of water or an aqueous solution comprising hydrophilic antioxidants with or without other surface-active additives at from 10 to 95&deg; C. to form a solubilized preparation having a carotenoid content of from 0.5 to 10% by weight.

Use of solubilized carotenoid preparations for coloring food preparations

Organosulfur compounds can be used in complexes with carotenoids for effecting a bathochromic shift in the absorption bands of carotenoids in the UV/vis spectrum. Carotenoid formulations comprising these complexes, a process for preparing these formulations and their use in the food, cosmetics and pharmaceutical sectors are described.

Production of carotenoid preparations in the form of

A method and an apparatus for determining diffusion parameters, concentration, size or flow behavior of particles in a sample, exciting light of a light source being directed into the sample, Raman scattered light being collected from an observed volume of the sample and being passed on to a spectrograph where it is resolved into spectral lines, the intensity of at least one spectral line being measured at least 10 times per second by means of one photodetector each, and the measured intensity values for the respective spectral line being used, via a fluctuation analysis, preferably an autocorrelation or a frequency analysis, to calculate diffusion parameters, concentration, size or flow behavior of the particle to which the spectral line in question can be assigned. With this method, it is also possible for signals of different spectral lines or bands, or signals of Raman scattered light, quasi-elastically scattered light and fluorescence light to be correlated with one another.

Method and apparatus for Raman correlation spectroscopy

An apparatus for carrying out laser-induced two-photon fluorescence correlation spectroscopy (TPA-FCS), in which a plurality of volumes (6) are delimited or defined in the apparatus in such a way that samples (3) introduced into these volumes can be excited and observed in parallel by means of a single laser (1). Such an apparatus is e.g. used to screen active compounds.

Apparatus for parallelized two-photon fluorescence correlation

Process for the production of fine-particle, essentially amorphous dye or drug preparations by converting a relatively coarse-particle dispersion or a solution into a colloidal dispersion in water, where the colloidal dispersion is generated at a temperature above the melting point of the dye or drug by admixing appropriately hot water (where appropriate under pressure) or an aqueous protective colloid solution so that an emulsion of a melt in aqueous medium is produced and is immediately spray-dried or converted by cooling into a suspension.
