Abstract: The invention relates to a reactor assembly (1) for an industrial water analysis device (2), particularly using a high temperature oxidation method, the reactor assembly (1) comprises an outer reactor tube (6) and an inner reactor tube (8), the inner reactor tube (8) being removably inserted into the outer reactor tube (8). The invention further relates to an industrial water analysis device (2) comprising a housing (4) and the aforementioned reactor assembly (1), wherein the outer reactor tube (6) is fixedly mounted to the housing (4). Moreover, the invention relates to an inner reactor tube (8) for the reactor assembly (1).

Abstract: A sample analysis appliance for the analysis of a sample solution, in particular of contaminated water or of waste water, with a reaction vessel for the thermal digestion of a portioned sample of the sample solution to be analyzed. The reaction vessel has an injection port for the introduction of the sample into the reaction vessel, at least one sample solution storage vessel for the device-internal storage of sample solution, and an injection syringe device which is movable between the sample solution storage vessel and the reaction vessel and which can be controlled to collect the sample from the sample solution storage vessel and introduce the sample into the injection port of the reaction vessel.
