奧特IBD (intrinsically base deactivated) 柱
可以說(shuō)是功能zui全面的色譜柱。它能同時(shí)分析酸性,堿性和中性化合物的混合物,而且峰形不會(huì)拖尾。其在它的固定相烷基鏈中含有一個(gè)極性官能團(tuán),
這個(gè)官能團(tuán)對(duì)化合物的分離及色譜保留都會(huì)起作用。此官能團(tuán)可以與硅膠表面的羥基相互作用,使得奧特IBD色譜柱在末端未封閉的情況下,也可以消除色譜峰拖尾現(xiàn)象,并可以同時(shí)分析酸性、堿性、兩性及其他極性混合物。
奧特IBD 柱分析堿性化合物時(shí)在不需要加入調(diào)節(jié)劑的情況下,色譜峰形依然很尖銳,這也是奧特IBD 柱用于LC/MS 分析的一個(gè)很大優(yōu)勢(shì)。
奧特IBD 柱同樣適合分析酸性化合物。這種色譜柱的固定相兼有極性和非極性的特點(diǎn)。所以?shī)W特IBD 柱的應(yīng)用方式有兩種(正相和反相)(Figure 2); 當(dāng)分析酸性化合物時(shí),一般采用反相分離模式,這樣固定相中的極性官能團(tuán)可以與酸性化合物相互作用,增加其保留能力。
奧特IBD色譜柱對(duì)親水性化合物的保留能力很好,這是普通C18的一個(gè)很好的補(bǔ)充。
液相色譜柱廠家,Ultra IBD 液相色譜柱廠家 與其他色譜柱比較的特點(diǎn)是:
¨ 雖然末端沒(méi)有封閉,由于采用了先進(jìn)的鍵合技術(shù),色譜峰形依然尖銳、對(duì)稱
¨ 專為同時(shí)分析極性與非極性混合物設(shè)計(jì)
