Abstract
The present invention relates to a split stream flow cell which is used for a UV detector of liquid chromatography and in which a UV light for detecting absorption of the light is transmitted through a sample solution flowing in the cell. It is an object of the present invention to reduce the influences of both the flow effect and the liquid lens effect without cell volume being made too large. To this end, a split stream flow cell of the present invention comprises a split flow channel (12) which passes through a cell block (10) and which has a central portion communicating with an inlet channel (18), both ends communicating with an outlet channel (38), and both sides symmetrical with respect to the central portion, the diameter thereof being increased from a given position in the central portion toward both ends.
