粗孔硅胶在气相色谱中的核心价值在于其对永久气体和轻烃卓越的分离能力，尤其是在工业过程控制、安全监测和石油化工领域，它是一个经典、可靠且经济的选择。在作为载体使用时，则为分析极性样品提供了一个高负载量、高强度的平台。
粗孔硅胶在气相色谱中主要用作气-固色谱（GSC）的固体吸附剂，或者作为气-液色谱（GLC）的惰性载体。其核心特点是具有较大的孔径（通常指孔径>10 nm，或100 Å）和较大的比表面积，使其特别适合分离永久性气体和低分子量（C1-C4）烃类。
实例1：永久性气体的分析
应用场景：高纯气体（如氦气、氩气）中杂质的检测、空气成分分析、煤矿瓦斯气体（CH₄、CO₂、O₂、N₂）的快速分析、环境监测中的温室气体分析。
具体实例：煤矿瓦斯气体的分离
实例2：低碳数烃类异构体的分离
应用场景：石油化工中的炼厂气分析、天然气成分分析、聚合级乙烯/丙烯中杂质的检测。
具体实例：C1-C4烃类混合物的分离
粗孔硅胶对于分离正构烷烃、异构烷烃、烯烃非常有效。例如，可以很好地分离：
乙烷、乙烯、乙炔。
丙烷、丙烯。

The core value of coarse pore silica gel in gas chromatography lies in its excellent separation ability for permanent gases and light hydrocarbons, especially in industrial process control, safety monitoring, and petrochemical fields. It is a classic, reliable, and economical choice. When used as a carrier, it provides a high loading capacity and high strength platform for analyzing polar samples.
Coarse pore silica gel is mainly used as a solid adsorbent for gas-solid chromatography (GSC) or as an inert carrier for gas-liquid chromatography (GLC) in gas chromatography. Its core characteristics are its large pore size (usually referring to pore size>10 nm, or 100 Å) and large specific surface area, making it particularly suitable for separating permanent gases and low molecular weight (C1-C4) hydrocarbons.
Example 1: Analysis of Permanent Gases
Application scenarios: detection of impurities in high-purity gases such as helium and argon, analysis of air composition, rapid analysis of coal mine gas (CH ₄, CO ₂, O ₂, N ₂), and greenhouse gas analysis in environmental monitoring.
Specific Example: Separation of Coal Mine Gas
Example 2: Separation of Low Carbon Number Hydrocarbon Isomers
Application scenarios: Refinery gas analysis, natural gas composition analysis, and detection of impurities in polymer grade ethylene/propylene in the petrochemical industry.
Specific example: Separation of C1-C4 hydrocarbon mixtures
Coarse pore silica gel is highly effective in separating n-alkanes, isoparaffins, and olefins. For example, it can be well separated:
Ethane, ethylene, acetylene.
Propane and propylene.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the "Application of Spherical Coarse Pore Silica Gel Chromatography Packing in Shimadzu" for the separation and determination of non methane total hydrocarbons, light hydrocarbons, carbon dioxide, refrigerants, fluorocarbons, and other pollutants in fixed pollution source exhaust gas, achieving good results.
