Flow analysis instrument for measuring gas composition

classification

A chemical gas analysis instrument table.It measures the composition of the gas in terms of changes in the amount of ions or currents caused by chemical reactions.In order to improve the selectivity, prevent measuring electrode surface contamination and maintain electrolyte performance, diaphragm structure is generally used.The commonly used electrochemical type analyzer has the constant potential electrolysis type and galvani battery type two kinds.The working principle of constant potential electrolytic analyzer is to apply a specific potential on the electrode, and the measured gas will produce electrolytic effect on the electrode surface. As long as the potential added to the electrode is measured, the unique electrolytic potential of the measured gas can be determined, so that the instrument has the ability to select and identify the measured gas.Galvani battery type analyzer is to pass through the diaphragm and diffused into the electrolyte gas electrolysis, measurement of the electrolytic current generated, can determine the concentration of the gas measured.By selecting different electrode materials and electrolyte, the internal voltage on the electrode surface can be changed to realize the selectivity of gas with different electrolytic potentials.

An analytical instrument operating according to the selective absorption of different components of gases to different wavelengths of infrared.The type of gas can be distinguished by measuring the absorption spectrum.The concentration of the gas measured can be determined by measuring the absorption intensity.Infrared analyzer can be used in a wide range, not only to analyze the composition of gas, but also to analyze the composition of solution.The inspection part of the infrared gas analyzer commonly used in industry consists of two parallel optical systems of the same structure.

Packaging equipment

The headspace analysis instrument is used for the determination of oxygen and carbon dioxide content and mixing ratio in sealed packaging bags, bottles, cans and other packages.Suitable for production line, warehouse, laboratory and other occasions to quickly and accurately evaluate the content and proportion of gas components in packaging, so as to guide production and ensure the shelf life of products.
