✦ Synopsis

A method to produce a new type of disposable tube detector for water analysis IS described

The tube detectors are composed of capdlarles filled with sol-gel glasses doped with orgamc reagents When a solution IS sampled through a tube detector, speck contammants form chromophorlc groups with the orgamc reagents that are embedded m the sol-gel glasses, formmg a stamed sectlon of the glass bed The speclfx advantages of doped sol-gel glasses for use as disposable tube detectors Include transparency, low cost, low leachmg and easy control of the glass charactenstlcs, mcludmg hgand capacity, pore-size dlstnbutlon and pellet dlmenslons DetectIon of several metals m aqueous solution 1s demonstrated Keywords Colorlmetrlc glass detectors, Disposable tube detectors, Length of stain detectors, Sol-gel glasses, Water
