Waters色譜柱186003975
SymmetryShield RP18,是以沃特世*的一步合成技術(shù)制造的屏蔽型固定相。它可以顯著改善堿性化合物峰形，并且提供與C18柱不同的分離選擇性.SymmetryShield RP18色譜柱采用的極性基團(tuán)嵌入技術(shù)又稱屏蔽型固定相技術(shù)，是在通常的C18鏈中引入特定的極性基團(tuán)所得到的新型固定相。大量研究表明，極性官能團(tuán)可有效阻擋有機(jī)堿與硅膠表面殘余硅羥基的不良作用，因而其峰形比相應(yīng)的C18柱更優(yōu)。同時(shí)，這類固定相允許使用全水流動(dòng)相而不會(huì)發(fā)生“相塌陷"現(xiàn)象，因而可用于分離許多親水性化合物SymmetryShield RP18常用規(guī)格訂貨信息如下：
