Abstract

An apparatus for measuring the properties of a sample includes a sensor block with at least one sensor module whose housing contains a measuring chamber in contact with a sensor, the housing of the sensor module M including a mixing chamber for indirect measurement of a sample property, which chamber is placed upstream of the measuring chamber, and is connected with a sample channel and a reagent channel. Due to the modular design of the sensor block, the sample and reagent paths in the sensor block or sensor module may be kept short; along with the compact arrangement of mixing chamber and measuring chamber this permits the required sample and reagent volumes to be kept to a minimum.
