Analysis of Hydrophilic Molecules in Biological Fluid with Novel Mixed-Mode Column
June 1st 2008In pharmaceutical development, it is important to analyze small molecules or their metabolites in biological fluids. For this purpose, the analytical methods such as sample pretreatment, 2D-LC and LC–MS have been developed. However there are still problems of resolution and protein adsorption. As a result, satisfying analytical results have not always been achieved.
