GDX-104二乙烯苯、苯乙烯等共聚物
苯乙烯和二乙烯基苯的交联共聚物或其他共聚物的多孔小球，可作为气固色谱的固定相直接使用，也可作为气液色谱的载体。引入不同极性官能团后，可构成非极性、中等极性和强极性等不同种类的高分子多孔小球
用作色谱固定相能使强极性化合物如醇、酸、酯、醛、脯、卤代烷、含氮氧化物及烯烃、芳烃等得到很好的分离。水的峰形陡而对称,同时保留值极小
气相色谱固定相 GDX-104
粒度:80-100目 25g
最高温度:250°C
应用:非甲烷总烃的测定，焦炉煤气，炼厂气，天然气，变压器油，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
