ABSTRACT:
A method for detecting and determining a volatile or volatilizable substance in an aqueous solution or liquid and an apparatus employed for this method are disclosed. The volatile component, vaporized from the solution through a water repellent and gas permeable membrane, is brought into contact with a dried or partially dried transparent film-like color developing carrier which is provided adjacent to the membrane, and the determination is carried out by the degree of color-change of the carrier. The apparatus comprises a cover plate with sample holes, a membrane, a color developing carrier, and a cover plate with observation windows. The members are fitted tightly together to form a single composite layer.
