Abstract: The present invention relates to a method of and a vertical pumping device (1) for internally distributing Hg in a fluorescent tube body (3). The bottom (7) of the fluorescent tube body (3) is closed. The device (1) arranges, in a first position, a first solid body (9?) comprising a predetermined first amount of bound Hg. The device (1) arranges, in a second position, a second solid body (9?) comprising a predetermined second amount of bound Hg. A first release (E1) of the first amount of Hg is achieved in the fluorescent tube body (3) by gasification with heat and under pressure for purification of contaminant particles in the fluorescent tube body. A second release (E2) of the second amount of Hg is achieved in the fluorescent tube body (3) by gasification attained for the occluded mercury vapour of the fluorescent tube body (3).

Abstract: A system for colorimetric titration, comprising a container (10); a mixing device (11), which is arranged to extend along a substantial portion of a longitudinal axis of the container (10); and an analysis arrangement (12) having a housing in the form of a collar which is adapted to fit around and at least partially enclose, a section of said container extending in a plane substantially perpendicular to the longitudinal axis of the container and not intersected by the mixing device (11) in the container (10). The collar houses at least one electromagnetic radiation source, arranged to emit electromagnetic radiation towards said container (10); and at least one electromagnetic radiation detector, arranged to detect electromagnetic radiation, emitted from the at least one electromagnetic radiation source through the container (10).

Abstract: A collecting device to be connected to at least one test tube, in which a sample is subjected to a wet combustion process, comprising a collector tube, which is arranged to collect and draw off from the test tube steam products from the wet combustion process. The collecting device further comprises at least one connecting tube, which has a first opening connecting the connecting tube to the collector tube and a second opening which is adapted to be inserted into the test tube. The collector tube comprises at least one projection extending from the interior of the collector tube to have a condensing sur-face for condensation of reagent in the steam products.
