| Abstract: | A procedure is proposed for the generation of standard gas mixtures of volatile organic substances based on chromatomembrane gas extraction with the use of composite carbon-fluoroplastic matrices. The regularities of this process were found, and an adequate physicochemical model was developed. The advantages of the proposed procedure over traditional bubbling and chromatomembrane gas extraction on unmodified matrices were demonstrated. |
