产品简介

三键键合的酰胺基(Amide)键合相、宽泛的流动相pH条件

详细信息

自从2003年，沃特世就已经开发出创新的固定相用于亲水作用色谱分离，以克服对强极性化合物难以保留和分离的挑战性问题。基于沃特世新颖BEH颗粒技术，ACQUITY UPLC BEH Amide柱使用化学稳定耐受的、三键键合的酰胺基(Amide)键合相，从而为HILIC分离在稳定性与通用性方面又开创了新维度。

ACQUITY UPLC BEH Amide柱能够使用宽泛的流动相pH条件(2-11)，从而可以对在极性、分子结构和pKa值性质上跨越大的极性分析物混合物实现优异的保留与分离。

Analysis of Free Bromate Ions in Tap Water using an ACQUITY UPLC BEH Amide Column


SensitivityTo establish reliable data, it is recommended that the analytical method be at least 10-fold more sensitivethan the action limit imposed for the assay. By following the 10 ppb WHO guideline for bromate, this wouldrequire that the analyte be detectable at 1 ppb or lower. Typical IC methods can detect bromate at these verylow levels; however, the methods used for IC are more labor intensive and require a rigorous instrumentmaintenance schedule due to the reagents used for the post-column reaction. In contrast, HILIC chromatography coupled with MS detection provides both ease of use and high sensitivity. Figure 1 shows single ion recording(SIR) MS chromatograms in the range of 0.05 - 1 ppb. The mass-to-charge ratio monitored for the bromate ion was 128.9 Da.
