較強(qiáng)極性的GDX-501、GDX-502型氣相色譜固定相

? ? ? ? 在生產(chǎn)合成中GDX-501、GDX-502都是引入了-CN基團(tuán)的較強(qiáng)極性的色譜填料,且在GDX系列填料中使用廣,比較而言, GDX-501的極性要強(qiáng)物GDX-502, 較深的顏色和較強(qiáng)的靜電作用也反映出它的強(qiáng)極性,而GDX-501的孔徑要小于GDX-502。應(yīng)用方面,如C4烯烴異構(gòu)體、CO、CO2等分析測(cè)定,國(guó)外同類型產(chǎn)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.
