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
高纯硅胶:
Purospher STAR的高纯硅胶品质出色,金属杂质含量不到5ppm,其硅胶表面健合覆盖技术使得它可以在获得很好的峰对称性的同时,拥有非常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。
