Abstract

The method involves directing a radiation beam into the liquid, detecting (10) the radiation re-emerging from the liquid and determining the type and concentration of the additives from the radiation. Gas bubbles in the liquid are influenced so as to be essentially arranged in a plane. The liquid is set into a rapid circular motion by a device immediately before a measurement section (13). Independent claims are also included for the following: an arrangement for implementing the method.
