Integrated chemical analyzing system


A micro-chemical analyzing system integrating chemical sensors and fluid control elements.

A blood gas monitoring microsystem and an integrated chromatography system are manufactured as integrated chemical analyzing systems. A blood gas monitoring microsystem analyzes the pH of blood samples obtained intermittently from the body. One example of such a system integrates a microvalve, a pH ion sensitive field effect transistor (pHISFET), and other components on a silicon substrate. In the integrated chromatography system separation and analysis components are based on the difference in the adsorption among sample components. This system is commercially available in a shape that a number of valves, sensors, and columns (tubes) are integrated on a silicon substrate.
