METHOD AND APPARATUS FOR SENSING SUBSTANCES BY ANALYSIS OF ADSORBED MATTER ASSOCIATED WITH ATMOSPHERIC PARTICULATES

摘要

A method and apparatus for sensing substances, such as mineral deposits, in which atmospheric particulates in an area being investigated are collected, and adsorbed matter is removed from the particulates. The adsorbed matter (usually in the gaseous state) is then analyzed to provide information concerning the possible existence of the substance in the area being investigated.
