Packed column for determination of oxygen and nitrogen in the air
Packed column for determination of oxygen and nitrogen in the air Details:



Name: Packed column

Specification: 3m*1/8

Model: 5? molecular sieve

Application: Determination of methane concentration in ambient air by gas chromatography

Air, the "gas of life" we breathe every day, is layered on the surface of the earth, transparent, colorless and odorless. It is mainly composed of nitrogen and oxygen and has an important impact on human survival and production.
Air refers to the mixed gas in the earth's atmosphere, so air is a mixture, which is mainly composed of nitrogen, oxygen, rare gases (helium, neon, argon, krypton, xenon, radon), carbon dioxide and other substances (such as water vapor, impurities, etc.) Become. The volume fraction of nitrogen is about 78%, the volume fraction of oxygen is about 21%, the volume fraction of rare gases (helium, neon, argon, krypton, xenon, radon) is about 0.934%, and the volume fraction of carbon dioxide is about 0.04% (2017 data), the volume fraction of other substances (such as water vapor, impurities, etc.) is about 0.002%. The composition of air is not fixed. As altitude changes and air pressure changes, the composition ratio of air will also change. But people have long believed that air is a single substance. Later, French scientist Lavoisier first came to the conclusion that air is composed of oxygen and nitrogen through experiments. At the end of the 19th century, scientists discovered through a large number of experiments that there are rare gases such as helium, argon, and xenon in the air.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd., using new technology, developed a 5? molecular sieve packed column for the determination of O2 and N2 in the air. The column efficiency is high, the separation is good, and the results are satisfactory.
