较强极性的GDX－501、GDX-502型气相色谱固定相
在生产合成中GDX－501、GDX－502都是引入了－CN基团的较强极性的色谱填料，且在GDX系列填料中使用广，比较而言， GDX－501的极性要强物GDX－502, 较深的颜色和较强的静电作用也反映出它的强极性，而GDX－501的孔径要小于GDX－502。应用方面，如C4烯烃异构体、CO、CO2等分析测定，国外同类型产品包括Hayesep C、 Chromosorb 104等。

GDX-501 and GDX-502 gas chromatography stationary phases with strong polarity
In production synthesis, GDX-501 and GDX-502 are chromatographic fillers with strong polarity that introduce - CN groups, and are widely used in the GDX series of fillers. In comparison, GDX-501 has stronger polarity than GDX-502, and its darker color and stronger electrostatic effect also reflect its strong polarity. The pore size of GDX-501 is smaller than that of GDX-502. In terms of application, such as the analysis and determination of C4 olefin isomers, CO, CO2, etc., similar products abroad include Hayesep C, Chromosorb 104, etc.
