USE OF AN INTERACTION BETWEEN A GAS AND A LIQUID FOR THE SAMPLING OF GASEOUS AND PARTICULAR ELEMENTS FROM A GASEOUS MEDIUM FOR THEIR ANALYSIS

摘要

P The invention relates to the use of a method for carrying out an interaction between a gas and a liquid and comprising: a) the introduction, into an enclosure traversed from bottom to top by the gas in a gaseous flow continuous and comprising an element subdividing this gaseous flow into a plurality of gaseous threads, of a volume of the liquid intended to interact with the gas above this element, b) keeping this volume of liquid in suspension above said element element, thanks to the bubbles formed by said gaseous threads in contact with said volume of liquid, for a suitably chosen time, and c) the collection of the volume of liquid having thus interacted with the gas, for the removal of the gaseous and / or particulate elements present in a gaseous medium for the qualitative and / or quantitative analysis of these elements. The invention also relates to the use of an apparatus for performing an interaction between a gas and a liquid for the sampling of gaseous and / or particulate elements present in a gaseous medium for the purpose of their qualitative and / or quantitative analysis. Applications: control and monitoring of air pollution and the quality of atmospheres. /P
