Twenty phenylthiohydantoin-amino acide (PTH-AA) are separated by micellar capillary electrophoresis in 13.5 min. A low-energy krypton fluoride laser ise used in a thermooptical absorbance detector to produce typical detection limits (3σ) of 9×10 -7 M PTH-glycine injected in a 0.6-nL volume, corresponding to 0.5 fmol (100 fg) of PTH-glycine injected onto the capillary. Detection limits are roughly 3 orders of magnitude superior conventional liquid chromatographic determinations
