Abstract: A sample preparation device is useful for preparing a sample of a process fluid, and the device contains a removal device; a filter unit, which is designed to filter the sample of the process fluid in such a way that the filtered sample of the process fluid is substantially free of any turbidity; a feed device; and also a temperature control device, which is designed to control the temperature of the sample of the process fluid in such a way that the temperature of the sample of the process fluid is substantially constant while it is being fed.

Abstract: The invention relates to a transportable sample drawing container for drawing a sample of a fluid contained in a process container, said sample drawing container being adjustable between a sample drawing position and a transport position. In the sample drawing position, at least one closable opening which is arranged at a first end section of the sample drawing container and which leads into the interior of the sample drawing container is open, and in the transport position, a sample chamber which is arranged in the interior is closed in a fluid-tight manner, wherein the sample drawing container can be inserted into a movable lock fitting. The invention additionally relates to a sample drawing system comprising the sample drawing container and a lock fitting and to a method for drawing a sample using the sample drawing system.

Abstract: (EN) The invention relates to a special LIBS measurement tube focusing unit, referred to simply as LIBS measurement tube, for vertically dipping into a material to be analyzed, which material is moved in a horizontal flow, characterized in that the measurement tube extends vertically and is internally hollow and open at least at the bottom end, such that a bottom edge is formed at the bottom end, the measurement tube has an inlet for coupling in a laser beam and an outlet for coupling out an emission spectrum at the upper end, the measurement tube is constructed in such a way that, in the measurement tube, the laser beam is focused at the material to be analyzed, specifically bulk material, in particular raw, intermediate, and end products from the processing of potash, magnesium, rock salt, or evaporated salt, but without additional scattering and deflection occurring, such that a plasma of the material to be analyzed is produced within the measurement tube by the laser radiation and the emission spectrum of the material to be analyzed reaches the outlet for outcoupling through the interior of the measurement tube, and scrapers (1, 2) lie on the inner and outer focusing tube wall annularly, preferably at the same vertical height on the focusing tube (3), which scrapers are arranged in such a way that the scrapers can be moved vertically in relation to the focusing tube (3), such that material to be analyzed that adheres to the focusing tube (3) on the inside and outside in the lower region can be scraped off by a relative motion of the focusing tube (3) in relation to the scrapers (1, 2).
