SEPARATING COLUMN, ESPECIALLY FOR A MINIATURISED GAS CHROMATOGRAPH

摘要

The invention relates to a separating column, especially for miniaturised gas chromatograph. In addition to a micro-chromatograph provided with one or more inventive separating column. The inventive separating column prevents the known racetrack effect and can therefore be produced in a simple and economical manner. The separating column ( 1 ) comprises a channel ( 2 ) for a flow of fluid having analysate molecules. The flow of fluid comprises counter flowing curves ( 3, 4 ) with turning points ( 7, 8 ), the average diameter of the channel ( 2 ) is greater than the length of the path traversed by an analysate molecule when diffused between two turning points ( 7, 7 a; 8, 8 a).
