1. A system for analyzing a plurality of liquid samples, said system comprising:
- a system base;
a plurality of test elements arranged in a linear array, with each test element having a test field which produces a detectable change when contacted by a liquid sample containing a material to be detected;
a storage container containing the plurality of test elements therein, said storage container being removably received in the system base, said storage container having an opening for said test elements to be removed therefrom;
a measuring device attached to said system base for detecting the detectable change produced in a test element of said plurality of test elements;
sealing means attached to said system base, said sealing means comprising a plurality of individual pressing means which seals individual test elements of the plurality of test elements by applying pressure thereto, said pressing means fittingly entering a corresponding recess in corresponding test elements of said plurality of test elements.

Abstract
A system for analyzing sample liquids using dry reagents is configured for the determination of clinical parameters. The system including an analysis instrument containing the test elements to carry out the test. Form and design of the test elements are adjusted for use in the analysis system. The system is utilized for analyses where available test elements which are in contact with their environment exhibit a low storage stability.

11. A method of analyzing a liquid sample comprising the steps of:
-
providing a system having a system base with a plurality of test elements arranged in a linear array, with each test element having a test field which produces a detectable change when contacted by a liquid sample containing a material to be detected; providing a storage container containing the plurality of test elements therein, said storage container being removably received in the system base, said storage container having an opening for the test elements to be removed therefrom; providing a measuring device attached to the system base for detecting the detectable change produced in a test element of the plurality of test elements; providing a releasable sealing means attached to the system base, with the releasable sealing means sealing the opening by pressingly engaging the storage container wherein the storage container can be pressed between the sealing means and the system base to seal the opening; removing pressure from the releasable sealing means to open the opening of the storage container; transporting the first test element of the test element linear array from the storage container to a measurement site; closing the opening with the sealing means; applying liquid sample to a test field of the first test element at the measurement site, the test field producing the detectable change when contacted by a material in the liquid sample; detecting a sample-induced change of the test field; calculating a measurement based on the detected change; displaying the measurement on a display; and removing the used first test element from the test element array. - View Dependent Claims (12, 13, 14)
