Abstract
An optode designed to prevent washing away of the indicator and reagent from a membrane is located within an optical device that measures substance concentrations. The reagent and indicator materials are covalently bound on the membrane. The membrane can be a polysaccharide, especially cellulose, an acid glycol ester, or it can contain silicon. The indicator and/or reagent can be covalently bound to the membrane by a bridge molecular, particularly a multifunctional aldehyde, glutaraldehyde or a silane.
