GDX-403色谱柱主要以二乙烯苯与含氮杂环单体的共聚物作为固定相。高分子多孔聚合物材料使其具有一些不错的特点：

中等极性：这使得它对极性和非极性化合物都有一定的分离能力，应用面较广。

较高的比表面积：约有 280 m²/g，提供了较多的作用位点。

热稳定性较好：*高使用温度可达 250°C，能满足多数常规气相色谱分析的需求。

化学稳定性良好：适用于分析多种化合物。

主要应用领域

GDX-403色谱柱的特性决定了它特别擅长以下几类分析：

水分分析：尤其是微量水分的测定，例如化工产品中的微量水。

活性气体和挥发性有机物：常用于水、低级胺（如甲胺、乙胺）、甲醛等的分析。

工业过程控制与质量检验：例如工业甲醛溶液中微量甲醇的测定、水合肼的测定等

The GDX-403 chromatographic column is a commonly used medium polarity packed column in gas chromatography analysis, particularly suitable for the analysis of certain specific compounds.
The GDX-403 chromatographic column mainly uses a copolymer of divinylbenzene and nitrogen-containing heterocyclic monomers as the stationary phase. Polymer porous materials have some good characteristics:
Medium polarity: This gives it a certain ability to separate polar and non-polar compounds, and has a wide range of applications.
Higher specific surface area: about 280 m ²/g, providing more active sites.
Good thermal stability: The maximum operating temperature can reach 250 ° C, which can meet the needs of most conventional gas chromatography analyses.
Good chemical stability: suitable for analyzing various compounds.
Main application areas
The characteristics of the GDX-403 chromatographic column determine its particular expertise in the following types of analysis:
Moisture analysis: especially the determination of trace moisture, such as trace water in chemical products.
Reactive gases and volatile organic compounds: commonly used for analysis of water, lower amines (such as methylamine, ethylamine), formaldehyde, etc.
Industrial process control and quality inspection: for example, determination of trace methanol in industrial formaldehyde solution, determination of hydrazine hydrate, etc
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the "GDX-403 Filled Chromatography Column Application PE580" for the determination of trace amounts of methanol and hydrazine hydrate in industrial methanol solutions, with high column efficiency, good separation, and satisfactory results.
