Physicists from St. Petersburg State University (SPbSU) and specialists from Kazan National Research Technical University named after A.N. Tupolev have developed a unique device for gas analysis. It combines the functions of a plasma detector and a chromatograph. This innovation significantly improves the accuracy of research.
For effective monitoring of the atmosphere, it is necessary to simultaneously investigate several parameters, which requires a comprehensive approach to optimize time and resources. Scientists have combined two devices into one analytical tool and demonstrated its high efficiency.
The "PIA" chromatograph determines the composition of gas mixtures by finding hydrocarbons, alcohols, hydrogen sulfide, and inorganic compounds such as nitrogen and oxygen. The innovative plasma detector operates on the principles of plasma electron spectroscopy (PLES). It analyzes substances by examining electrons released from atoms under the influence of plasma.
Scientists explained that components may have similar physical or chemical properties in complex mixtures. This makes it difficult to separate them. With the help of the new device, specialists will be able to more accurately distinguish overlapping signals.
The developed device separates the gas mixture into individual components, performs analysis based on chemical, physical properties, and the time it takes to pass through the system. The device increases the accuracy of measuring impurity concentrations in a portable chromatograph. According to the authors of the device, this opens up new horizons for technologies in ecology, medicine, and industry.
