A detector cell for measuring the absorption of ultraviolet and/or visible radiation in substantially liquid samples, comprising: a) base pan with a groove channel system including a channel piece which is defined by a base region surface and a top face surface, both of which surfaces reflect the measuring radiation, and b) a lid part, including an inlet opening and outlet opening for the introduction and removal of a sample, and an entry opening and exit opening for ultraviolet and/or visible measuring radiation, wherein said lid part and base part are cooperatively aligned to define an interaction region wherein the sample may be introduced from the inlet opening, pass through the groove channel system and exit the outlet opening, and also wherein the measuring radiation may be introduced from the entry opening, pass through the channel piece of said groove channel system and exit the exit opening.
