Method for analyzing a sample from a process with on-line capillary electrophoresis apparatus and capillary electrophoresis apparatus

摘要

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.
