    詳細(xì)介紹
    Lichrospher 液相色譜柱
    Lichrospher為廣大色譜分析工作者提供了大量的技術(shù)文獻(xiàn)和資料。目前，Lichrospher 可以提供從適合分析普通疏水性化合物的健合相，到適合分離極性化合物的健合相，同時(shí),擁有經(jīng)典的專門適合分離堿性化合物的色譜柱—— Lichrospher RP-select B。

    Lichrospher 填料參數(shù)：
    德國Merck Lichrospher 色譜柱

    Lichrospher 60 RP-select B － 堿性化合物分析柱：
    作為專門適合分離分析堿性化合物的色譜柱，其鍵合相為改性C8疏水基團(tuán)，60?的孔徑使得其健合相密度比常規(guī)色譜柱高出很多，從而使得硅膠表面的硅醇基團(tuán)暴露在流動(dòng)相中的幾率大大減少，如此堿性化合物的拖尾影響也將微乎其微。
    Lichrospher WP 300 RP-18e － 蛋白多肽專用分析柱：
    大分子蛋白的分析分離需要用到大孔徑的色譜柱，Lichrospher 系列提供經(jīng)典的300?孔徑的色譜柱。Lichrospher WP 300 RP-18e 對于蛋白和多肽具有良好的選擇性，其特殊的封端技術(shù)使得拖尾影響減少到最小
    Lichrospher PAH － 多環(huán)芳烴專用分析柱：
    Lichrospher PAH專門被設(shè)計(jì)根據(jù)EPA 620和EPA 550用來分離16種多環(huán)芳烴
    德國Merck Lichrospher 色譜柱
