13X分子筛填充柱是气相色谱中用于分离永久性气体的经典固定相，尤其在分离氧气(O₂)和氮气(N₂) 方面效果出色。它基于分子筛的规整孔道结构，对不同大小和极性的分子进行选择性吸附来实现分离。
分离原理：基于分子尺寸排阻和吸附强度差异。小分子（如O₂、N₂、CH₄、CO）可进入孔道被吸附，而大分子被快速洗脱；同时，13X分子筛的强极性表面对CO₂等分子吸附力极强。
对CO₂敏感：13X对CO₂有极强的不可逆吸附。若样品含CO₂，会使其永久“中毒”失效，通常需配合预柱或专用色谱柱系统。
对水敏感：水分子会强烈吸附在分子筛上导致柱效下降，因此样品和载气必须严格干燥。
典型应用：空分行业的气体纯度分析、石化工艺气检测、环境空气中CO/CH₄监测及制氢行业杂质分

The 13X molecular sieve packed column is a classic stationary phase used in gas chromatography for separating permanent gases, particularly effective in separating oxygen (O ₂) and nitrogen (N ₂). It is based on the regular pore structure of molecular sieves, and selectively adsorbs molecules of different sizes and polarities to achieve separation.
Separation principle: based on differences in molecular size exclusion and adsorption strength. Small molecules (such as O ₂, N ₂, CH ₄, CO) can enter the pores and be adsorbed, while large molecules are rapidly eluted; At the same time, the strongly polar surface of 13X molecular sieve has a strong adsorption force for molecules such as CO ₂.
Sensitive to CO ₂: 13X exhibits extremely strong irreversible adsorption of CO ₂. If the sample contains CO ₂, it will permanently "poison" and become ineffective, usually requiring the use of a pre column or specialized chromatographic column system.
Sensitive to water: Water molecules strongly adsorb onto the molecular sieve, leading to a decrease in column efficiency. Therefore, the sample and carrier gas must be strictly dried.
Typical applications: Gas purity analysis in the air separation industry, detection of petrochemical process gases, monitoring of CO/CH ₄ in ambient air, and impurity separation in the hydrogen production industry
