Title:
分散体からの粒子、とくに血液からの血球の分離方法および分離モジュール
Document Type and Number:
Japanese Patent JP4005022
Kind Code:
B2
Abstract:
A method for separating particles from a fluid dispersion, particularly for separating corpuscular components from biological samples, above all from blood. A separating module suitable for performing the method has a substrate with flow channels, comprising a feed channel for supplying the dispersion to a junction, a first drain channel for draining fluid having a reduced particle concentration away from the junction, and a second drain channel for draining fluid having an increased particle concentration away from the junction. The fluid flows so much faster in the second drain channel than in the first drain channel that due to the different flow speeds the dispersed particles preferentially flow at the junction further in the second drain channel.
