Continuous flow method.

摘要

A continuous flow method and apparatus in which a fluid stream comprising segments of liquids (R1 + S; R2; B) separated by intervening segments of immiscible fluid (A1; A min 2; A sec 2) eg gas, is flowed through a conduit (100). The conduit has three sequential sections (102, 104, 106). As the stream passes from the first (102) into the second (104) section, some of the liquid segments (R1 + S; R2) are caused to combine whereas others (R1 + S + R2; B) are maintained separate. In the third section (106), the combined segments (R1 + S + R2) are thoroughly mixed. The technique allows the mixing of selected liquid segments within the fluid stream, whilst maintaining separation of other segments, so permitting two-stage reactions to be performed without inter-sample carryover.
