        提高色譜柱的通用性,無論酸性、中性、堿性化合物都是最理想的選擇性,高穩定性,長壽命。

         
        Purospher RP-18 endcapped適合在中性條件下分析酸性和堿性化合物。
         
        Purospher  RP-18極性端基封尾,適合分析堿性化合物物,流動性可100%耐水,對極性化合物物有較好的分析。
         
        Purospher RP-18 HC不進行任何的封端,專門分析炸藥中所含的成分分析。

         

        高純硅膠:

        Purospher STAR的高硅膠品出色,金屬雜質含量不到5ppm,其完美的硅膠表面健合覆蓋技使得它可以在得極好的峰稱性的同,有極的耐高堿性流相的能力



        然硅膠和合成硅膠的區別:馨新儀器 
         
        右圖所示的是A硅膠的制備過程,我可以發現,M2O-nSiO2中,M所代表的是大量的價金屬元素,如Na, K, Fe等。用傳統的硅膠合成工,無法去除大量的金屬雜質,因此,在遇到分析堿性化合物或易生螯合作用的化合物,拖尾影響大,同,容易品被固定相基所吸附的情況。而采用B型硅膠的色柱,其硅膠制備的原料
        物質Si(OC2H ) 中幾乎不含任何金屬雜質,因此,選擇盡量B型硅膠的色譜柱。
         
        Purospher STAR 對已制得的B型高純硅膠采取特殊的表面覆蓋技術,使得C1 鍵合相在硅膠表面處彼此互相連接,以此起到即使在強酸、強堿流動相的條件下,也能大幅延長其使用壽命的作用。
         
         
         
        PH穩定性測試:
        Purospher STAR 具有極出色的PH定性,長時間的數據測試證Purospher STAR可以在PH 1.5-10.5的范定使用。
