Analytical Techniques Used in Monitoring of Atmospheric Air Pollutants

Modification of hydrophobic sorbents by cobalt chloride in order to concentrate low molecular polar organic substances from the air for subsequent gas chromatographic determination

“…Low molecular weight organic compounds, which are discussed in the article, are usually present in the air in their vaporized state. The main methods of concentrating vapors of volatile organic compounds (VOCs) are cryogenic concentration [1][2][3], solvent extraction, performed in the impinger [4] and denudors [5][6]; active [7][8] and passive [8][9] sorption of substances by sorbents contained in cartridges or tubes, as well as solid-phase microextraction (SPME) [10][11]. SPME and passive sampling are more suitable for prolonged atmospheric air control, rather than for monitoring the concentration of VOC in real time, because of their inherent slow mass transfer.…”

Application of passive sampling technique in monitoring research on quality of atmospheric air in the area of Tczew, Poland

“…One can distinguish three procedures in terms of analytics and monitoring of BTEX compounds in atmospheric air [20][21][22][23][24][25][26][27][28][29]:…”

The State of the Art in the Field of Non-Stationary Instruments for the Determination and Monitoring of Atmospheric Pollutants

“…At present, monitoring and evaluation of air quality is performed according to an act of studies. In our earlier papers, analytical techniques and selected examples of equipment used for collecting air samples, and analyses performed in the laboratory, were described (1,2).…”
