GDX-104二乙烯苯、苯乙烯等共聚物
苯乙烯和二乙烯基苯的交聯共聚物或其他共聚物的多孔小球，可作為氣固色譜的固定相直接使用，也可作為氣液色譜的載體。引入不同極性官能團后，可構成非極性、中等極性和強極性等不同種類的高分子多孔小球
用作色譜固定相能使強極性化合物如醇、酸、酯、醛、脯、鹵代烷、含氮氧化物及烯烴、芳烴等得到很好的分離。水的峰形陡而對稱,同時保留值極小

粒度:80-100目 ?25g
最高溫度:250°C
應用:非甲烷總烴的測定，焦爐煤氣，煉廠氣，天然氣，變壓器油，微量水分
GDX-104 copolymer of divinylbenzene and styrene
The crosslinked copolymer of styrene and divinylbenzene or the porous microspheres of other copolymers can be used directly as the stationary phase of gas-solid chromatography or as the carrier of gas-liquid chromatography. After introducing functional groups with different polarity, different kinds of polymer porous spheres with non-polar, medium polarity and strong polarity can be formed
As a chromatographic stationary phase, strong polar compounds such as alcohols, acids, esters, aldehydes, prolines, haloalkanes, nitrogen oxides, olefins and aromatics can be well separated. The peak shape of water is steep and symmetrical, and the retention value is minimal
Gas chromatography stationary phase GDX-104
Particle size: 80-100 mesh 25g
Maximum temperature: 250 ° C
Application: determination of non-methane total hydrocarbon, coke oven gas, refinery gas, natural gas, transformer oil, trace moisture
