空氣(Air),我們每天都呼吸著的“生命氣體”,它分層覆蓋在地球表面,透明且無色無味,它主要由氮氣和氧氣組成,對人類的生存和生產(chǎn)有重要影響。
空氣是指地球大氣層中的混合氣體,因此空氣屬于混合物,它主要由氮氣、氧氣、稀有氣體(氦、氖、氬、氪、氙、氡),二氧化碳以及其他物質(zhì)(如水蒸氣、雜質(zhì)等)組合而成。其中氮氣的體積分?jǐn)?shù)約為78%,氧氣的體積分?jǐn)?shù)約為21%,稀有氣體(氦、氖、氬、氪、氙、氡)的體積分?jǐn)?shù)約為0.934%,二氧化碳的體積分?jǐn)?shù)約為0.04%(2017年數(shù)據(jù)),其他物質(zhì)(如水蒸氣、雜質(zhì)等)的體積分?jǐn)?shù)約為0.002%??諝獾某煞植皇枪潭ǖ?,隨著高度的改變、氣壓的改變,空氣的組成比例也會改變。但是長期以來人們一直認(rèn)為空氣是一種單一的物質(zhì),直到后來法國科學(xué)家拉瓦錫通過實驗首先得出了空氣是由氧氣和氮氣組成的結(jié)論。19世紀(jì)末,科學(xué)家們又通過大量的實驗發(fā)現(xiàn),空氣里還有氦、氬、氙等稀有氣體。

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.
