The hyphenation of chiral capillary electrochromatography (CEC) with electrospray ionization mass spectrometry (ESI-MS) is very challenging but promising due to the fact that it combines sensitivity with high specificity and selectivity. In this work, CEC capillaries packed with (3R,4S)-Whelk-O1 chiral
