產(chǎn)品簡介

詳細(xì)介紹

XBridge BEH Shield RP18柱，除了C18鏈以外還包括一個親水的氨基甲酸酯官能團(tuán)(極性內(nèi)嵌)，從而對堿性分析物提供優(yōu)異的峰形,該色譜柱也提供相對于直鏈烷基色譜柱的其它選擇性。

XBridge色譜柱被創(chuàng)造成為具有pH耐受能力的HPLC固定相商品。那些宣稱通過特殊表面修飾手段獲得高pH耐受力的色譜柱，根本無法與XBridge色譜柱的柱壽命表現(xiàn)相提并論。產(chǎn)品穩(wěn)定性與生俱來于BEH顆粒的合成工藝中。在加速pH10穩(wěn)定性測試條件下，將XBridge C18柱與某些見的色譜柱以及那些號稱具有高pH穩(wěn)定性的色譜柱相比較，數(shù)據(jù)清楚表明，XBridge C18柱超出其他色譜柱(XTerra)壽命10倍以上，色譜性能的降低微乎其微。

使用XBridge BEH Shield RP18色譜柱改進(jìn)美國藥典（USP）度他雄胺分析方法
