Using a HiTrap™ column and a low pressure pump
HiTrap 是通用电气医疗集团生命科学部著名品牌之一，于1991 年上市。HiTrap 柱的预填充模式获得了巨大的成功，为以往费力的色谱柱层析提供便利和节省时间。
1991 年最初上市的六种色谱柱分别为：HiTrap Protein A HP、HiTrap Protein G HP、HiTrap Heparin HP、HiTrapChelating HP、HiTrapBlue HP 以及HiTrap NHS-actived HP。
多年以后，诸多成功的色谱柱加入到HiTrap 产品家族，为学术研究者和工艺研发者们提供了较广的选择范围。
到2011 年2 月，HiTrap 家族将会增至135 种不同的层析柱产品，涵盖了最常用的色谱分析技术-脱盐、亲和、离子交换色谱（IEX）和疏水相互作用色谱法（HIC）。
此类产品受欢迎程度较高，试想一下，如果我们把2010 年在全球所卖出的所有HiTrap 层析柱首尾相连，则这些层析柱的整体长度约为5000 米左右（3 英里多），这真是太让人吃惊了！
