- the invention relates in particular to a modular measuring device which, depending on the requirements, can be used offline, online or even inline.
- adapted optical components and sample preparation and transport modules enables the processing of dry and liquid samples, but also in compact form (for example, cuts) or images.
- BESTATIGUNGSKOPIE In many chemical and process engineering processes, production is controlled with the typical parameters such as temperature, pressure, viscosity, throughput, etc., primarily for safety reasons. Increasingly high demands on product quality and demands for yield increases resulting from economic reasons have also led to the development and use of special measuring methods that are able to assess the chemical and physical quality of the material produced.
- image processing methods are used in addition to classifying and optical extinction or scattered light methods.
- Measuring devices are known which are used in the laboratory, but also online or inline in the production process.
- different preparation methods mechanical and optical components such as conveyors, stirrers, ultrasonic dispersers, flow cells, objective, camera, microscope, light guide, light source, etc. are used.
- the above-described image processing methods have several disadvantages.
- known measuring devices are designed for the respective application and can be used only in very narrow application and measuring range limits.
- microscopically finest materials for example, normal or inverted microscopes with different optics and illumination devices are used, which allow only small working depths, small observation surfaces and short working distances and thus allow little leeway for different sample preparation and sample transport.
- Other devices allow only the processing of dry or liquid dispersed materials, or are optimized for quiescent or moving materials. Often the known methods are sensitive to vibration and not robust and flexible enough for operational use.
- Object of the present invention is therefore to provide a universal, robust and designed in a modular design image processing analysis or measuring device, which allows the simplest means of adaptation to very wide application and measuring range limits.

- the at least one sample carrier and / or an image-receiving device in particular in the form of a camera, is fixedly or displaceably arranged on this base holding device, which can be rotated or swiveled by a drive device.
- the individual components arranged on the base holding device can be moved by means of suitable actuators.
- a drive unit can serve, for example, as a Z drive for automatically focusing a camera. It is also possible for a camera to have several objectives, such as normal, microscopic and telecentric lenses, which are optionally assigned to the objective Camera are vorschaltbar. Likewise, different filters can be automatically connected upstream of the camera.

It is also possible to provide at least one second holding device on the stand, which is fixedly arranged on the stand or is also rotatably and / or displaceably arranged on the stand by means of suitable drives. Sample carriers, camera feed devices, light sources, etc. can also be arranged on this further holding device.
- sample carrier in the context of the invention can glass plates, flow cells, reactors, etc. are used.
- sample carriers can be moved or adjusted by means of a mechanical stage, or by means of suitable mechanically, hydraulically or pneumatically driven sample carrier transport systems, in particular in the object plane.
- Sample containers, mixing and dispersing devices, transport systems such as e.g. Pump, vibrating chute, dosing screw, belt, blower, can be arranged on the tripod or the base holding device.
- Sample preparation modules for dispersion, dilution to measurement concentration in the liquid or gas-borne state, sample or image transport can also be provided.
- a data processing system for the evaluation, visualization and storage of the results with interface in an over- ordered network completes the analysis device according to the invention.

- a sample carrier a transparent and opaque sample plate can be used as a sample carrier.
- the sample holder holding device accommodates the sample plate, which can easily be exchanged and is very easy to clean, aligned in the object plane and transports the suspension to be measured through the object plane at an easily adjustable angle of inclination.
- the angle of inclination is determined by the viscosity and the desired layer thickness of the sample stream.
- the glass plate for example, can advantageously be adapted to the interfacial properties of the suspension by various types of coatings.
- Open sample transport avoids the problems of particle blockage and the minimum layer thicknesses imposed by the largest particles in closed cuvettes, which cause great problems with the depth of field.
- the measuring device advantageously has constant, pulsed or triggered light sources of different wavelength, intensity and propagation direction.
- the light is transmitted in reflected light, transmitted light, brightfield, darkfield and in different directions, and in combination with adapted optics, such as normal, microscope or telecentric lenses, provides a sharp and high-contrast image of the sample in one or more, preferably used digital b / w or color cameras.
