    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。
