Shimadzu 2014五A填充柱应用于岛津上测定氢，氧，氮，一氧化碳，甲烷2m*4mm*3mm

五A分子筛、
化学式：3/4CaO·1/4Na2O·Al2O3·2SiO2·9/2H2O（也有资料给出的是3/4CaO·1/4Na2O·Al2O3·2SiO2·4.5H2O，这可能是由于制备方法和条件的不同导致的微小差异）。
中文名：五A分子筛。
外文名：五A Molecular Sieve。
孔径：约5Å（1Å=0.1纳米），即0.5纳米。这意味着它可以吸附分子直径小于0.5纳米的任何分子。
二、吸附性能
1、吸附原理：五A分子筛的吸附原理与色谱法相似，但它并不改变物质的分子组合。它是通过分子水平下的物质吸收来实现对特定分子的吸附。
2、吸附量：五A分子筛可以吸附多达自身重量22%的水分，显示出其强大的吸附能力。
3、吸附选择性：5A分子筛对正构烷烃等具有优先吸附性。然而，对于结构相似的醇类，如乙醇和异丙醇，5A分子筛没有明显的选择性吸附差异，因此一般不用于这类物质的分离。
三、主要用途
1、天然气处理：用于天然气干燥、脱硫和脱除二氧化碳。
2、气体分离：用于氮氧分离、氮氢分离，以制备氧气、氮气和氢气。
3、石油工业：用于石油脱蜡，以及从支链烃和环烃中分离出正构烃。
4、变压吸附：特别适用于变压吸附工艺，可适应各种大小的制氧、制氢、制二氧化碳等气体变压吸附装置。

5A molecular sieve
Chemical formula: 3/4CaO · 1/4Na2O · Al2O3 · 2SiO2 · 9/2H2O (some sources also provide 3/4CaO · 1/4Na2O · Al2O3 · 2SiO2 · 4.5H2O, which may be due to slight differences in preparation methods and conditions).
Chinese name: 5A molecular sieve.
Foreign name: 5A Molecular Sieve.
Aperture: Approximately 5 Å (1 Å=0.1 nanometers), which is 0.5 nanometers. This means that it can adsorb any molecule with a diameter less than 0.5 nanometers.
2、 Adsorption performance
1. Adsorption principle: The adsorption principle of 5A molecular sieve is similar to chromatography, but it does not change the molecular combination of the substance. It achieves adsorption of specific molecules through the absorption of substances at the molecular level.
2. Adsorption capacity: 5A molecular sieve can adsorb up to 22% of its own weight of water, demonstrating its strong adsorption ability.
3. Adsorption selectivity: 5A molecular sieve has preferential adsorption properties for n-alkanes and other substances. However, for structurally similar alcohols such as ethanol and isopropanol, 5A molecular sieves do not show significant differences in selective adsorption, and therefore are generally not used for the separation of such substances.
3、 Main purpose
1. Natural gas processing: used for natural gas drying, desulfurization, and removal of carbon dioxide.
2. Gas separation: used for nitrogen oxygen separation and nitrogen hydrogen separation to prepare oxygen, nitrogen, and hydrogen.
3. Petroleum industry: used for dewaxing petroleum and separating normal hydrocarbons from branched and cyclic hydrocarbons.
4. Pressure swing adsorption: Especially suitable for pressure swing adsorption processes, it can adapt to various sizes of gas pressure swing adsorption devices for oxygen production, hydrogen production, carbon dioxide production, etc.
