Apparatus for measuring the components of a sample
First Claim
1. An apparatus for measuring chemical and physico-chemical properties of a sample, comprisinga sensor block with at least one sensor module for indirect measurement of at least one sample property, said sensor module comprising a housing which contains a sample channel and a measuring chamber which is contacted by a sensor,a removable mixer part containing a mixing chamber with a magnetic stirrer and having at least one connection for said sample and a reagent medium and a channel leading into said measuring chamber, said mixer part being positionable in said housing of said sensor module, andtwo magnetic conductors positioned in said mixer part which are connectable with a magnetizing coil and are directed towards said magnetic stirrer in said mixing chamber, wherein for indirect measurement of at least one of said sample properties said sample and said reagent medium are mixed in said mixing chamber.

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.
