Patent ID: 7182911

Claim:
A chemical analysis system comprising: a means for spotting a sample liquid onto a first chemical analysis element for measuring the concentration of a specific component contained in the sample liquid, a means for spotting a sample liquid and a reference liquid onto a second chemical analysis element for measuring the activity of a specific ion contained in the sample liquid, an incubator in which the first chemical analysis element spotted with the sample liquid and the second chemical analysis element spotted with the sample liquid and the reference liquid are placed and which holds the first and second chemical analysis elements at respective constant temperatures, a concentration measuring means which is provided to measure the concentration of the specific component contained in the sample liquid by measuring the optical density of the color formed by the coloring reaction of the sample liquid and a reagent on the first chemical analysis element after incubation in the incubator, an ionic activity measuring means which is provided to measure the ionic activity of the specific ion contained in the sample liquid after incubation in the incubator, and a temperature control means for automatically maintaining the first chemical analysis element at a first predetermined temperature suitable for measuring the optical density of the color formed by the coloring reaction and holds the second chemical analysis element at a second predetermined temperatures suitable for measuring ionic activity, wherein the first predetermined temperature and the second predetermined temperature are differentiated by making an amount of heat transmitted to the first chemical analysis element different from that transmitted to the second chemical analysis element, and wherein the temperature control means comprises a heating means that cooperates with a first pressing member and a second pressing member.
