Abstract
A method and apparatus for conducting chemical reactions at a liquid-solid interface wherein a reaction component is fixed on the surface of a solid phase immersed in a liquid phase containing a freely diffusing, mobile reaction component. The apparatus comprises a substantially smooth-surfaced matrix of appropriate geometrical configuration designed to provide a large surface to volume ratio, a short transfer distance from the mobile component to the fixed component distributed on the solid phase surface and to drain freely upon removal from the reaction liquid.
