提高色谱柱的通用性,无论酸性、中性、碱性化合物都是最理想的选择性,高稳定性,长寿命。

 
Purospher RP-18 endcapped适合在中性条件下分析酸性和碱性化合物。
 
Purospher  RP-18极性端基封尾,适合分析碱性化合物物,流动性可100%耐水,对极性化合物物有较好的分析。
 
Purospher RP-18 HC不进行任何的封端,专门分析炸药中所含的成分分析。

 

高纯硅胶:

Purospher STAR的高硅胶品出色,金属杂质含量不到5ppm,其完美的硅胶表面健合覆盖技使得它可以在得极好的峰称性的同有极的耐高碱性流相的能力



然硅胶和合成硅胶的区别:馨新仪器 
 
右图所示的是A硅胶的制备过程,我可以发现M2O-nSiO2中,M所代表的是大量的价金属元素,如Na, K, Fe等。用传统的硅胶合成工,无法去除大量的金属杂质,因此,在遇到分析碱性化合物或易生螯合作用的化合物,拖尾影响大,同,容易品被固定相基所吸附的情况。而采用B型硅胶的色柱,其硅胶制备的原料
物质Si(OC2H ) 中几乎不含任何金属杂质,因此,选择尽量B型硅胶的色谱柱。
 
Purospher STAR 对已制得的B型高纯硅胶采取特殊的表面覆盖技术,使得C1 键合相在硅胶表面处彼此互相连接,以此起到即使在强酸、强碱流动相的条件下,也能大幅延长其使用寿命的作用。
 
 
 
PH稳定性测试:
Purospher STAR 具有极出色的PH定性,长时间的数据测试证Purospher STAR可以在PH 1.5-10.5的范定使用。
