Waters ACQUITY UPLC CSH C18反相色谱柱
2010年,沃特世推出了新型表面带电杂化颗粒(CSH)技术,为杂化颗粒表面赋予少量正电荷。利用这一技术可以使用低离子强度的流动相(如0.1%甲酸体系)分析碱性化合物,而仍能获得卓越的峰形与载量。CSH技术还允许使用甲酸来替代TFA等离子对试剂,而仍保持带电分析物的良好峰形,对质谱分析尤为有利。

ACQUITY UPLC CSH C18柱克服了大多数现代C18柱在低离子强度流动相条件下因载量所导致的峰形差的问题。因带有严格控制下的、低水平的正表面电荷,ACQUITY UPLC CSH C18柱为碱性化合物提供行业领先的峰形,而无需使用离子对试剂。

产品特点

1. 通用型反相色谱柱。

2. 适用于低离子强度流动相条件下的液相分离(流动相与LC/MS条件相同)。

3. 快速平衡。

4. 碱性化合物峰形极佳,高载量。
