Abstract
The invention relates to a sample flow control member to be used particularly in a continuously operated analysis of liquid or slurry-like materials, said control member being provided with members for selectively conducting the sample flow to an analyser. According to the invention, the control member (1, 21, 41) is installed in an essentially horizontal position and provided with at least one moving member (11, 28, 42) in order to turn the control member (1, 21, 41) around its rotation axis (12, 29, 48) in order to selectively conduct the sample flow to at least one analyser (7, 27; 44, 46) through at least one aperture (5, 25, 49) provided in the wall of the control member (1, 21, 41).
