Analyzer having sensor with memory device
 An analyzer includes an exchangeable and consumable element such as a sensor, column or reagent the characteristic of which specifies an analyzing condition. The element is provided with a non-volatile semiconductor memory which holds an analyzing condition adapted for the element as data. When the element is mounted on an analyzer body, a controller of the analyzer reads the analyzing condition from the memory to update an analyzing condition inherently provided in the analyzer body. The result of analysis and/or operational history information of use of the element may be written into the memory with which the element is provided.
