一般說明

由于存在电负性氟,Ascentis Express F5 的五氟苯基丙基固定相可提供具有缺电子苯环的稳定反相填料。除了形成 pi-pi 和温和的空间相互作用外,F5 相也通过极性相互作用保留化合物。Ascentis Express F5 可用于碱性、酸性或中性化合物,选择性与 C18 不同。

Research shows that immunoassay techniques are not the best choice for the estimation of vitamin D in human blood samples. The main reasons are that some immunoassays are not able to distinguish between 25-OHD3 and 25-OHD2 vitamin D metabolites. Furthermore

文章

This study demonstrates the impact of various mobile phase modifiers on the separation; formate modifiers outperform acetate in terms of MS signals (or sensitivity) and chromatographic resolution.

This article highlights the impact that sample matrix effects can have on LC/MS response and discusses two novel approaches to reduce it.

Enhanced selectivity for stereoisomers and closely related compounds with alternate selectivity from C18 phases for basic, acidic, or neutral compounds
