Abstract
A new multichannel restrictor for supercritical fluid chromatography h as been developed. Four construction parameters (number, length and in ner diameter of channels, and their geometrical arrangement) can be va ried so that restrictors with different flow characteristics can be de signed. The effective ratio, L/d, in which L is the length of a channe l and d is the inner diameter, is about two orders lower than values a ssumed for porous frit restrictors.
