高純硅膠:

Purospher STAR的高硅膠品質(zhì)出色,金屬雜質(zhì)含量不到5ppm,其*的硅膠表面健合覆蓋技術(shù)使得它可以在得*的峰對(duì)稱性的同時(shí),有極強(qiáng)的耐高堿性流動(dòng)相的能力



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(jià)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(shí),拖尾影響較大,同時(shí),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(shí)盡量選用B型硅膠的色譜柱。

 

Purospher STAR 對(duì)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(qiáng)酸、強(qiáng)堿流動(dòng)相的條件下,也能大幅延長(zhǎng)其使用壽命的作用。
