Abstract

The Conway microdiffusion method, using a closed chamber system, allows the determination of substances susceptible to volatilization and appropriate fixing means. This system comprises two compartments located so that if one of them put the substance to volatilize and other appropriate fixative or trapping, airtight chamber when a stream of gas from the field will be set to release towards the fixation; current is given by the simple set of gas pressure differences on both surfaces. The body is isolated and then analyzed quantitatively by titration, potentiometry, photocolorimetry, etc.
