Patent DE-4407637-A1 (DE)
Inventor: BOELING GERD
IPC: G01N7/10
Filed: 1994-03-08
Abstract: An osmometric device is disclosed for determining the content of an analyte made up of one or several substances in a solution of mixed substances. The device consists of an osmotic cell (A) provided with a manometric device and mounted downstream of an osmotic cell (B). Both cells are separated by an inner membrane (a). The upstream cell (B) in turn has a second membrane (b). The second membrane (b) forms a part of a wall of a duct. The duct communicates with a supply line through which a solution suitable for setting the working pressure or the solution of mixed substances are selectively supplied. The inner membrane (a) is impervious to the analyte and permeable to the solvent, and the outer membrane (b) is permeable to the analyte and impervious to the remaining substances that make up the mixture of substances. The same non-permeating osmotic medium with the same osmolarity is contained in both osmotic cells in the initial or regenerated base state. This device allows an analyte content of a solution of mixed substances to be more quickly determined than it was possible in the state-of-the-art.
