Abstract

Measuring cell has a flow channel for an inert gas symmetrically formed on the outer ends of the main chamber (6). Preferred Features: The main chamber consists of a rectangular shaft (1) with a sample gas connection (2) centrally arranged on the lower side or upper side of the main chamber. The main chamber has a width of 160 mm and the flow channels have a rectangular inner cross-section of 20 x 40 mm2>.
