Abstract
With a method of establishing an enveloped flow in a channel, in the channel an envelopment area () with a channel section () is configured to which a stub with an outlet is connected, where the stub, which can be configured as a polyhedron, is arranged substantially at right-angles to the envelopment area and with the plane of the outlet substantially at right-angles to the channel section. An inlet channel () and an outlet channel () are connected to the envelopment area. By providing a narrowing-down in the cross-section of the channel in immediate extension of the envelopment area (), a hydrodynamic focussing of the sample fluid is achieved when a fluid, such as a sample fluid, is introduced into the stub, and a carrier fluid is introduced into the inlet channel. The advantage of the invention is that since it is necessary only to have two fluid inlets, a relatively simple structure can be established, which can be built up in a monolithic manner, e.g. by injection molding.
