Described is an apparatus for guiding an electromagnetic microwave, having: antenna surrounding walls, which define an interior space so as to surround therein at least an end region of an antenna of a microwave source, in particular laterally annularly as well as frontally; waveguide boundary walls, at least two of which are arranged in parallel to each other, wherein the waveguide boundary walls form a, in particular cuboid-shaped, waveguide having a substantially rectangular cross-section, wherein a cross-sectional plane is defined by a first direction that extends along a longitudinal direction of the antenna and a second direction that extends perpendicularly to the first direction, wherein it holds: 25&#x3e;a/b&#x3e;3, wherein a: is a width of the waveguide along the second direction, b: is a height of the waveguide along the first direction, wherein the apparatus is designed to let proceed a microwave from the interior space of the antenna surrounding walls into the waveguide.

A pressure reactor for treating a sample fluid includes an oven, a sample line partly arranged in the oven, and a pressure line arranged in surrounding relation to the sample line and partly arranged in the oven. The sample line has an outlet opening into the pressure line. A contamination blocking apparatus is disposed in the pressure line for forming a contamination barrier which has at least one section arranged between the outlet opening and the oven and which delimits a contamination-free region in the pressure line. The outlet opening of the sample line is arranged in the contamination-free region of the pressure line.
