Abstract

A system for the generation of a reference gas by the evaporation of a liquid in said gas, comprising an anhydrous gas line (11), an evaporation chamber (20) in turn comprising a microdrop generator (25) and fed by the an­hydrous gas line (11), the microdrop generator (25) being of the type in which microdrops (27) are generated and projected, in a controlled form, through a series of gen­erating elements (26).
