Coupling Capillary Electrophoresis With a Shifted Inlet Potential High-Resolution Ion Mobility Spectrometer. [PDF]

Electrophoresis
ABSTRACT We present the coupling of capillary electrophoresis to a custom‐built high‐resolution ion mobility spectrometer (IMS). This system integrates a shifted inlet potential IMS configuration with a customised nanoflow ESI sheath interface. It enables the rapid analysis of quaternary ammonium compounds (QACs) and their impurities in real‐world ...

Advances in capillary electro-chromatography

Journal of Pharmaceutical Analysis, 2019
Capillary electrochromatography (CEC) is a micro-scale separation technique which is a hybrid between capillary electrophoresis (CE) and liquid chromatography (LC). CEC can be performed in packed, monolithic and open-tubular columns.
