Porapak P 主要应用于气相色谱分析中,特别是以下领域:
水分的分析:
有机溶剂中的微量水分测定。
气体(如天然气、合成气、乙烯、丙烯等)中的水分含量分析。这是其在工业质量控制中的一个非常重要的应用。
极性小分子的分离:
永久性气体和轻烃的分离: 可以分离如氧气、氮气、一氧化碳、甲烷、二氧化碳等。虽然不如分子筛专门,但在某些复合填料方案中很常用。
含氧化合物的分析: 对甲醇、乙醇、甲醛、乙醛、甲酸、乙酸等有很好的分离效果。
溶剂分析: 用于分离醇类、酮类、酯类、卤代烃等混合溶剂。
特定行业应用:
石化行业: 分析乙烯、丙烯等聚合级单体中的微量水分和极性杂质。
环境监测: 分析空气或废气中的挥发性有机物,尤其是含氧VOCs。
食品和香料: 分析酒类、饮料中的醇、醛、酯等风味物质。
制药行业: 溶剂残留分析。

Porapak P is mainly used in gas chromatography analysis, especially in the following fields:
Analysis of moisture content:
Determination of trace moisture in organic solvents.
Analysis of moisture content in gases such as natural gas, synthetic gas, ethylene, propylene, etc. This is a very important application of it in industrial quality control.
Separation of Polar Small Molecules:
Separation of permanent gases and light hydrocarbons: can separate substances such as oxygen, nitrogen, carbon monoxide, methane, carbon dioxide, etc. Although not as specialized as molecular sieves, it is commonly used in certain composite packing schemes.
Analysis of oxygen-containing compounds: It has good separation effects on methanol, ethanol, formaldehyde, acetaldehyde, formic acid, acetic acid, etc.
Solvent analysis: used for separating mixed solvents such as alcohols, ketones, esters, halogenated hydrocarbons, etc.
Specific industry applications:
Petrochemical industry: Analyze trace amounts of moisture and polar impurities in polymerization grade monomers such as ethylene and propylene.
Environmental monitoring: Analyze volatile organic compounds, especially oxygen-containing VOCs, in the air or exhaust gas.
Food and spices: Analyze flavor compounds such as alcohols, aldehydes, esters, etc. in alcoholic beverages and beverages.
Pharmaceutical industry: solvent residue analysis.
