摘要

Measuring cell for determining the zeta - potential by means of flow potential - and flow current measurements and for the determination of data by means of atr - - ftir spectroscopy, consisting of a divided base body (1,2), on whose lower part (1) an atr - crystal (3), is placed on its top side, which with a sample can be completely or partially coated, an electrically non-conductive film (4) with two geometrically identically constructed recesses, the two form flow channels, is placed in a sealing manner and a cover plate (5) is positioned, the at least on the surface facing the flow channels with a sample can be completely or partially coated, the at least two openings to each of the two recesses of the film (4), wherein the openings in each case at the ends of the maximum dimension of the recesses are provided, as a result of a too - and discharge of liquid to the of the atr - crystal (3), in the film (4) and the cover plate (5) is realized in the form of a parallel flow channels formed, and this arrangement in a sealing manner of the upper part (2) of the base body is closed.,..
