Separation column, in particular for a miniaturized gas chromatograph

摘要

The present invention relates to a separation column, in particular for a miniaturized gas chromatograph, as well as a micro - chromatograph with one or more separation columns according to the invention. The separation column according to the invention prevents the so-called "race-track " - effect and is easily and cost-effectively in the production of. The separation column (1) has a channel (2) for a fluid flow with analysate molecules, of the oppositely directed curvatures (3, 4) with reversal points (7, 8), wherein the average diameter of the channel (2) is greater than the distance which a analysate molecule by diffusion in its path between the two reversal points (7, 7a; 8, 8a) travels.
