XTerra® OBD制取柱
化合物简洁：
杂化颗粒柱使制备纯化效力突飞大进
在不异的仪器和软件前提下，制备纯化的效力首要由所选用的制备柱的分手机能和上样量决议。XTerra®系列杂化颗粒柱许可您在1～12全pH规模试探吃瓜91 前提，以使方针峰与搅扰峰间的分手度*大，从而增添制备纯化时的粗品处置量。尤其主要的是，若方针化合物为无机酸或无机碱，制备任务者可有认识地挑选在使方针化合物不带电荷的活动相pH（无机酸在其pKa-2以下；无机碱在其pKa+2以上）停止分手前提的优化。此时因为完整消弭了高浓度阐发物同号离子间的静电排挤感化，无机酸碱表现出*大的制备上样量。如右图所示，三个碱**物在高pH前提下的上样量比低pH前提下可超出逾越80倍！
