Purospher STAR RP-18 endcapped、RP-8 endcapped、Si、NH2:
提高色譜柱的通用性,無(wú)論酸性、中性、堿性化合物都是理想的選擇性,高穩(wěn)定性,長(zhǎng)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(dòng)性可100%耐水,對(duì)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(mén)分析zha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,其硅膠表面健合覆蓋技術(shù)使得它可以在獲得非常好的的峰對(duì)稱性的同時(shí),擁有極強(qiáng)的耐高堿性流動(dòng)相的能力
天然硅膠和合成硅膠的區(qū)別:
上圖所示的是A型類硅膠的制備過(guò)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(wú)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。
PH穩(wěn)定性測(cè)試:
Purospher STAR 具有極出色的PH穩(wěn)定性,長(zhǎng)時(shí)間的數(shù)據(jù)測(cè)試證明Purospher STAR可以在PH 1.5-10.5的范圍內(nèi)穩(wěn)定使用。
