RTX-2330氣相柱
RTX-2330氣相柱 (熔融石英)
RTX-2330氣相柱 (高極性固定相；雙氰丙基氰丙基苯基聚硅氧烷)
? 順/反式脂肪酸甲酯、二氧（雜）芑同分異構體分析的通用柱。
? 溫度范圍: 0 °C~275 °C。
? 等同于USP G8和G48固定相。
Rtx®-2330固定相是極性*大的毛細管柱固定相。因為聚合物上接有氰
基，Rtx-2330固定相有極強的偶極距，并對順/反異構體化合物或共軛雙鍵化
合物具有很高的選擇性。但高極性柱在熱循環(huán)時一般熱穩(wěn)定性差、流失嚴重、
壽命較短。為了克服這些缺陷，我們采用一種新的表面處理技術，使其與Rtx-
2330所用的固定相更加相配。而且，我們改良的聚合物提升了柱的效率以及更
低的流失。
因為Rt®-2330固定相不是100%的鍵合相，所以不能用溶劑沖洗。
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.
