Evaluation of capillary liquid chromatography-electrospray ionization ion mobility spectrometry with mass spectrometry detection.

Due to the proteomics revolution, multi-dimensional separation and detection instruments are required to evaluate many peptides and proteins in single samples. In this study, electrospray ionization (ESI) ion mobility spectrometry (IMS) was evaluated as an additional separation after HPLC separations. Common HPLC mobile phase compositions (solvents, acid modifiers, and buffers) were assessed fo...

Chiral Capillary Electrophoresis - Mass Spectrometry

This review article addresses the developments and applications of capillary electromigration methods coupled on-line with mass spectrometry for chiral analysis. The multiple enantiomeric applications of this hyphenated technology are covered including chiral analysis of drugs, food compounds, pesticides, natural metabolites, etc., in different matrices such as plasma, urine, medicines, foods, ...
