Abstract

A system for analyzing sample liquids using dry reagents which is particularly suitable for the determination of clinical parameters. The system includes an analysis instrument containing the individually sealed test elements to carry out an analytical test. Shape and nature of the test elements were designed to match the analysis system. The system is particularly suitable for analyses where the available test elements exhibit a low storage stability when brought into contact with the environment.
