上海月旭（Welch）液相色谱柱
Ultimate LP-C18 液相分析柱
Ultimate® LP（LP代表英文Low pH首字母的缩写）子系列色谱柱，特别适合在极低pH至中等pH条件下分离极性化合物。系列该色谱柱延续了XB系列的优良特点，采用超纯全多孔球形硅胶，粒径、孔径分布均匀。LP-C18采用月旭特有的硅胶表面处理和固定相键合工艺进行填料生产，可在低pH条件下免受水解的作用，同时不封尾，避免了因封尾试剂在酸性条件下易水解而改变C18选择性的问题，使其在酸性流动相条件下具有更出色的分离性能、稳定性和更长的使用寿命。
- 1、允许在高温和低pH（0.5~8）条件下使用，具有最长寿命和最好重现性
- 2、无封尾：避免了因封尾试剂在酸性条件下水解造成的选择性改变
- 3、优势分离在常规C18上不能很好分离浓度差异大的两个物质（西药有关物质检测时主峰前后的杂质峰分离）
- 4、适用100%水做流动相
- 5、对极性强的化合物，具有很强的保留能力
- 6、可提供300Å孔径，以满足大分子生物如多肽、蛋白质的分离需求
