Multidimensional Separation Techniques for Characterization of Biotherapeutics

Multidimensional Separation Techniques for Characterization of Biotherapeutics

Ramesh Kumar;Anurag S. Rathore;Ira S. Krull
June 1st 2020

Multidimensional separations, in which two or more separation methods are coupled, are a valuable analytical tool for higher peak capacity and improved selectivity for the analysis of complex samples like biotherapeutics.

Practical Considerations for Capillary Electrophoresis–Mass Spectrometry for Analysis of Biotherapeutics

Ramesh Kumar;Anurag S. Rathore;Ira S. Krull
June 1st 2019

Coupling CE with MS presents some challenges. Here, we discuss the advantages of CE–MS over LC–MS, and the parameters that are important to obtain a stable CE–MS profile.
