Abstract
An analysis system for analyzing a biological fluid or the like for a constituent of the interest includes metal body structure with sample flow path channel structure that serially interconnects heater chamber structure, recess structure for receiving a reaction chamber cartridge and an analysis region to which a measuring system is coupled. The reaction chamber cartridge preferably includes reaction chamber structure with an immobilized enzyme in the reaction chamber that is capable of converting the constituent of interest to a constituent detectable by the measuring system. Cooperating with the metal body structure is a transparent face plate structure which permits visual observation of the sample flow path in the metal body structure. Thermally coupled to the metal body immediately adjacent the analysis region are a temperature sensor that provides a temperature signal to a control unit and a thermal source that receives control signals from the control unit as a function of signals from the temperature system for stabilizing the temperature of the metal body structure (including the reaction chamber structure, the heater chamber and the analysis region) at a desired analysis…
