method and apparatus for performing geochemical exploration by means of analysis of atmospheric particulates

摘要

A method and apparatus for performing a rapid geochemical survey over an area of the earth consisting of collecting and concentrating atmospheric particulates, preferably transferring the particulates into a stream of an inert carrier gas, heating the particulates to break down organic particles into particles of smaller size and vapours, removing from the stream inorganic particles which generally are of relatively high mass, and then analyzing the remaining organic particles and vapours to detect the presence of elements or compounds indicative of underlying geological conditions.
