Rtx®-2330 RTX-2330气相柱的详细资料

RTX-2330气相柱(高性固定相；双氰丙基氰丙基苯基聚硅氧烷) 顺/反式脂肪酸甲酯、二氧（杂）芑同分异构体分析的通用柱。 温度范围: 0 °C~275 °C。RTX-2330气相柱 固定相是性大的毛细管柱固定相。因为聚合物上接有氰基，RTX-2330气相柱 固定相有强的偶距，并对顺/反异构体化合物或共轭双键化合物具有很高的选择性。但高性柱在热循环时一般热稳定性差、流失严重、寿命较短。为了克服这些缺陷，我们采用一种新的表面处理技术，使其与Rtx-2330所用的固定相加相配。而且，我们改良的聚合物提升了柱的效率以及

低的流失。因为Rt®-2330固定相不是的键合相，所以不能用溶剂冲洗。

Rtx-2330 is one of the most polar capillary column stationary phases. Cyano groups on both sides of the polymer backbone give the phase a strong dipole moment and high selectivity for cis/trans compounds or compounds with conjugated double bonds. Highly polar columns typically exhibit poor column efficiencies, high bleed, and short column lifetimes when thermally cycled. To overcome some of these problems, we developed a surface treatment that is more compatible with the Rtx-2330 phase. In addition, our improved polymer produces columns with better column efficiency and lower bleed.
