GDX-301在气相色谱中的应用高度集中于工业气体中极性化合物的分离和环境样品中挥发性有机物的富集，同时也展现出在固相萃取等前处理领域的应用潜力。
生物体液中的药物提取（固相萃取）：在一项固相萃取研究中，GDX-301被用作吸附剂来提取尿液和血液中的吗啡。结果显示，在特定pH条件下，对吗啡的回收率可达90%以上，是一种简单、高效、低成本的萃取方法。
分离富集重金属离子：GDX-301还可作为萃取色层的支持体，用于富集废水中的痕量铅和镉，之后用原子吸收法进行测定，回收率在96-104%之间
GDX-301的大比表面积使其成为富集空气中挥发性有机物的良好吸附剂。
富集空气中的有机化合物：一项1997年的研究系统测定了GDX-301对醇类、饱和烃、芳香烃、酯类和卤代烃等20多种低分子量化合物的吸附与脱附参数。研究推荐在35℃下用2g GDX-301采样管采样，在180℃下热脱附，此条件能有效富集目标物（除甲醇外），展现了其作为空气采样吸附剂的价值。
富集水中痕量芳烃：GDX-301多孔微球也用于富集水中的痕量芳烃化合物。使用环己烷作为脱附剂，富集后的洗脱液可直接进行气相色谱分析，从而大大提高检测灵敏度

The application of GDX-301 in gas chromatography is highly focused on the separation of polar compounds in industrial gases and the enrichment of volatile organic compounds in environmental samples, while also demonstrating potential in pre-treatment fields such as solid-phase extraction.
Drug extraction from biological fluids (solid-phase extraction): In a solid-phase extraction study, GDX-301 was used as an adsorbent to extract morphine from urine and blood. The results showed that under specific pH conditions, the recovery rate of morphine could reach over 90%, making it a simple, efficient, and low-cost extraction method.
Separation and enrichment of heavy metal ions: GDX-301 can also be used as a support for extraction chromatography to enrich trace amounts of lead and cadmium in wastewater, and then determined by atomic absorption spectrometry with a recovery rate between 96-104%
The large specific surface area of GDX-301 makes it a good adsorbent for enriching volatile organic compounds in the air.
Enrichment of organic compounds in the air: A 1997 study systematically measured the adsorption and desorption parameters of GDX-301 for over 20 low molecular weight compounds, including alcohols, saturated hydrocarbons, aromatic hydrocarbons, esters, and halogenated hydrocarbons. The study recommends using a 2g GDX-301 sampling tube for sampling at 35 ℃ and thermal desorption at 180 ℃. This condition can effectively enrich the target substance (except methanol), demonstrating its value as an air sampling adsorbent.
Enrichment of trace aromatic compounds in water: GDX-301 porous microspheres are also used to enrich trace aromatic compounds in water. Using cyclohexane as a desorbent, the enriched eluent can be directly analyzed by gas chromatography, greatly improving detection sensitivity
