Abstract

Dispositivo óptico visual para el control de la halitosis Se refiere a un sensor colorimétrico de la halitosis sensible a los compuestos volátiles de azufre. Dicho sensor comprende un soporte sólido y un reactivo colorimétrico redox sensible a los compuestos volátiles de azufre. Se refiere también a un dispositivo para la detección de la halitosis que comprende dicho sensor situado en el interior de un tubo transparente. Dicho dispositivo sufre un cambio de color visualmente perceptible cuando la concentración de compuestos volátiles de azufre en la muestra gaseosa analizada es superior a 200 ppb, preferentemente superior a 250 ppb.
