Reaction Vessel, Reaction Vessel Arrangement and Method for Analyzing a Substance

A reaction vessel (1) for analyzing a substance, comprising:

• a storage chamber (2) with a circular cross section and
• at least one measuring chamber (3),
• wherein the storage chamber (2) and the measuring chamber (3) are interconnected in a transition area (UB) and are intended to receive the substance,
• wherein the measuring chamber (3) has several pairs of two opposing, plane-parallel measuring windows each (F1, F2;
• F3, F4;
• F5, F6;
• F7, F8) composed of a transparent material successively configured in plane-parallel levels in the axial direction of the reaction vessel (1) and/or transversely to this axial direction,
• wherein a distance (A1, A2, A3, A4) between the measuring windows of a pair (F1, F2;
• F3, F4;
• F5, F6;
• F7, F8) is different from a distance (A2, A3, A4, A1) between the measuring windows of the remaining pairs (F3, F4;
• F5, F6;
• F7, F8;
• F1, F2).

A process for analyzing a substance located inside a reaction vessel (1), the reaction vessel comprising:

• a storage chamber (2) with a circular cross section and
• at least one measuring chamber (3),
• wherein the storage chamber (2) and the measuring chamber (3) are interconnected in a transition area (UB) and are intended to receive the substance,
• wherein the measuring chamber (3) has several pairs of two opposing, plane-parallel measuring windows each (F1, F2;
• F3, F4;
• F5, F6;
• F7, F8) composed of a transparent material successively configured in plane-parallel levels in the axial direction of the reaction vessel (1) and/or transversely to this axial direction,
• wherein a distance (A1, A2, A3, A4) between the measuring windows of a pair (F1, F2;
• F3, F4;
• F5, F6;
• F7, F8) is different from a distance (A2, A3, A4, A1) between the measuring windows of the remaining pairs (F3, F4;
• F5, F6;
• F7, F8;
• F1, F2);
• wherein the process comprises processing and optically examining the substance inside said reaction vessel (1).
