Summary

A flow injection manifold is described based on a flow-through arrangement of thermistors for measuring heat effects of chemical reactions. Temperature changes down to 10−3 °C can be measured reproducibly. The working range for the determination of a component is dependent on the reaction enthalpy and can vary from 10−3 to 10 mol/l for acids and bases, from 10 to 1000 ppm for e.g., alkylhydroperoxides. Sample frequencies up to 150 samples per hour can be realized.
