Analyte focusing by micelle collapse is investigated as an on‐line sample preconcentration technique in partial‐filling MEKC with detection using UV and ESI‐MS. Enhancement in peak height sensitivity of more than a 100 was obtained for model alkylphenylketones and dialkylphthalates using analyte focusing by micelle collapse‐partial‐filling MEKC with UV or ESI‐MS detection.
