Summary:Disclosed is a method and apparatus by which a sample can be taken from a process and be analyzed on-line by means of a capillary electrophoresis apparatus. On the feed side of the capillary electrophoresis unit ( 13 ) the sample is continuously collected via a duct ( 16 ) from the process into the sample feeding system and fed into the capillary ducts ( 2, 3 ) through the same duct as is the feed solution, and all the solutions ( 16, 17, 18, 19 ) both on the feed side and on the exit end of the capillary electrophoresis unit ( 13 ) are pumped through the flow ducts, and the liquids flown through the capillary are removed on the exit end of the capillary electrophoresis unit ( 13 ) by means of a liquid treatment system.
