Abstract: The invention relates to a double-façade arrangement (1) for a construction (70), in particular a building, a bridge support, a bridge pier or a noise barrier wall, comprising a double façade (20) for generating a vertically directed air flow (50) by means of the chimney effect. Here, the double façade (20) comprises an inner façade (21) and an outer façade (22), wherein a façade interspace (23) for guiding the air flow (50) is situated between the inner façade (21) and the outer façade (22), wherein the inner façade (21) delimits the façade interspace (23) towards the construction (70), and the outer façade (22) delimits the façade interspace (23) towards the surroundings (60) of the construction (70).

Abstract: The invention relates to a coupling device for thermogravimetric analysis for coupling a thermogravimetric analysis with a spectroscopic analysis, comprising a housing with a connecting element by means of which said housing can be connected in a gas-tight and detachable manner to a sample chamber of a device for gravimetric analysis. The coupling device comprises at least two flange bushings or at least two adsorption elements which are detachably connected to the coupling device and comprise, on a first side, a condensation surface or an adsorption body for gaseous components. A screen is arranged on the coupling device such that it lies between the at least two flange bushings or the at least two adsorption elements and the sample chamber, wherein the screen has at least one opening.
