Abstract

A separator for separating liquid phase from a mixture thereof with solid phase, comprises a first conduit (52) through which the mixture is passed and a lateral second conduit (54) joined to the first conduit via a filter (56). Liquid is pumped from the first conduit through the filter into the second conduit, solid phase being retained by the filter. Means (70, 72) for backwashing the filter is provided. In continuous-flow analysis, the mixture in the first conduit is segmented by air or air and wash liquid, and the backflow washing is controlled to occur when an air or wash flow segment in the first conduit is in contact with the filter. The filter may be of sintered glass particles. Protuberance 64 serves to direct the liquid phase onto the filter 56. <IMAGE>
