Novel approach for process control and drug analyses with on-line capillary electrophoresis system

The increasing demands for "real-time" on-line monitoring of various biological, environmental and process samples and the need to measure concentrations of individual compounds at the same time require robust instrumentation with high separation efficiency and sensitivity. Summation of total compound amount, quick tests with unselective markers or antigens and development of computer simulation will need on-line and real-time multi-component analyses. Encouraging results have already been obtained in coupling of both a commercial CE instrument and real-time working on-line CE instrument to pulp and paper processes.The system set-ups will help to oversee actual changes in production. This poster shows examples about the use of on-line CE instrument in determination of inorganic ions and organic acids in water samples taken from pulp and paper machines, as well as about the separation of diuretics imaging their analyses from patient urine samples.
