Porapak QS 填充柱是一款功能强大、用途广泛的色谱柱，尤其擅长解决水与有机溶剂分离的难题。它在化工、环保、食品、医药等领域的气相色谱分析中扮演着重要角色。当您的分析方法开发遇到水峰干扰问题时，Porapak QS 通常是一个shou选的解决方案。

Porapak QS 是沃特世公司 生产的 Porapak 系列多孔聚合物填充柱中的一种。它本质上是一种由乙基乙烯基苯和二乙烯基苯共聚物组成的球形颗粒。这种材料是疏水性的，但对极性分子仍具有良好的分离能力。
2. 主要特点
固定相： 乙基乙烯基苯-二乙烯基苯共聚物。
极性： 弱极性到中等极性。
*高使用温度： 通常为 250°C。在高于此温度下使用会导致固定相降解和柱效下降。
特点：
亲水性： 对水有很强的保留，能够将水峰与大多数常见有机溶剂（如醇、酮、酯、烃类）的峰很好地分离开。这是它的应用之一。
惰性： 对活性化合物（如甲醛、硫化氢等）的吸附性较低，能获得对称的峰形。
多孔结构： 具有均匀的孔结构，通过尺寸排阻和吸附作用分离物质。

Porapak QS packed column is a powerful and versatile chromatographic column, particularly adept at solving the problem of separating water from organic solvents. It plays an important role in gas chromatography analysis in fields such as chemical engineering, environmental protection, food, and medicine. When your analysis method development encounters water peak interference issues, Porapak QS is usually a preferred solution.
Porapak QS is one of the Porapak series porous polymer packed columns produced by Waters Corporation. It is essentially a spherical particle composed of a copolymer of ethylvinylbenzene and divinylbenzene. This material is hydrophobic, but still has good separation ability for polar molecules.
2. Main features
Fixed phase: Ethylene vinyl benzene divinylbenzene copolymer.
Polarity: weak polarity to moderate polarity.
Maximum operating temperature: usually 250 ° C. Using above this temperature can cause degradation of the stationary phase and a decrease in column efficiency.
Features:
Hydrophilicity: It has strong retention of water and can effectively separate the water peak from the peaks of most common organic solvents, such as alcohols, ketones, esters, and hydrocarbons. This is one of its most famous applications.
Inert: Has low adsorption capacity for active compounds such as formaldehyde, hydrogen sulfide, etc., and can obtain symmetrical peak shapes.
Porous structure: It has a uniform pore structure and separates substances through size exclusion and adsorption.
Name: Filler Column
Material: Stainless steel
Model: Porapak QS
Specification: 4m * 3mm, 60-80 mesh
Maximum operating temperature: 250 ° C
Application: Analyze polar substances such as gases, water, alcohols, aldehydes, ketones, diols, etc
Application:
