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(jìn)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的高純硅膠品質(zhì)出色，金屬雜質(zhì)含量不到5ppm，其完美的硅膠表面健合覆蓋技術(shù)使得它可以在獲得極好的峰對稱性的同時，擁有極強的耐高堿性流動相的能力 天然硅膠和合成硅膠的區(qū)別： 右圖所示的是A型類硅膠的制備過程，我們可以發(fā)現(xiàn)，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(tǒng)的硅膠合成工藝，無法去除大量的金屬雜質(zhì)，因此，在遇到分析堿性化合物或易發(fā)生螯合作用的化合物時，拖尾影響較大，同時，容易發(fā)生樣品被固定相基質(zhì)所吸附的情況。而采用B型硅膠的色譜柱，其硅膠制備的原料 物質(zhì)Si(OC2H ) 中幾乎不含任何金屬雜質(zhì)，因此，選擇色譜柱時盡量選用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(shù)，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(wěn)定性測試： Purospher STAR 具有極出色的PH穩(wěn)定性，長時間的數(shù)據(jù)測試證明Purospher STAR可以在PH 1.5-10.5的范圍內(nèi)穩(wěn)定使用。
