ABSTRACT:
The invention concerns a NMR measuring cell, in particular one for a flow-through probe head (1) and having at least a first inlet opening (10) to introduce a first injected or pumped reaction liquid into the measuring cell (1) and a second inlet opening (11) for introduction of a second injected or pumped reaction liquid into the measuring cell (1). The measuring cell (1)is subdivided by means of an at least partially movable wall (2) into at least a first chamber (17) which communicates with the first inlet opening and a second Chamber (19) which communicates with the second inlet opening (11). The at least partially movable wall (2) is configured and adapted in such a fashion that directed motion thereof leads to a mixing together of the first reaction liquid separately stored in the first chamber (17) with the second reaction liquid separately stored in the second chamber (19). In accordance with the invention a rapid and homogeneous mixing-together of the two reaction liquids is achieved in milliseconds.
