Ecological Systems and Devices Annotation << Back About a sampling role in the quantitative chemical analysis of objects of surrounding environment. Part 3. Air Voronich S.S. Grebenkin N.N. Roeva N.N. Zaytsev D.A. The article focuses on the role of sampling in the quantitative chemical analysis of the atmosphere. It defines the concept of aspiration, discusses types of aspiration method of sampling (in the absorption devices on solid sorbents for hemosrbenty and filters) and their main disadvantages as well as used by adsorbing devices and materials. In particular, the report discusses in some detail of solid sorbents and chemisorbents, the classification of the aerosol filters, such as AFA. Possibilities of sampling the limited capacity of vessels (containers) of different volume from 1.0 to 2.0 liters recommended for studying air with a high content of various volatile at ordinary temperature hydrocarbons by gas chromatography and gas chromatography-mass spectrometry; particular choice of location of measuring points and the conditions under which a sample reflects the most likely nature of the medium under investigation. Keywords: Sampling the air; aspiration; absorptive device; solid sorbent; chemisorbent filter; pipette; canister. Contacts: E-mail: s-v80@mail.ru Pp. 08-14.
