Purospher STAR RP-18 endcapped、RP-8 endcapped、Si、NH2：

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的高纯硅胶品质出色，金属杂质含量不到5ppm，其完美的硅胶表面健合覆盖技术使得它可以在获得极好的峰对称性的同时，拥有极强的耐高碱性流动相的能力

天然硅胶和合成硅胶的区别：

上图所示的是A型类硅胶的制备过程，我们可以发现，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艺，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发生螯合作用的化合物时，拖尾影响较大，同时，容易发生样品被固定相基质所吸附的情况。而采用B型硅胶的色谱柱，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，选择色谱柱时尽量选用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稳定性，长时间的数据测试证明Purospher STAR可以在PH 1.5-10.5的范围内稳定使用。

长期柱寿命测试：
