## Abstract The determination of noble metals in environmental samples is of increasing importance. Palladium is often employed as a catalyst in chemical industry and is also used with platinum and rhodium in motor car catalytic converters which might cause environmental pollution problems. Two dif

A unique preconcentrator was constructed for on-line preconcentration using capillary electrophoresis generating concentration detection limits for peptides in the mid-picomolar range. Several common sheathless electrospray configurations were constructed in conjunction with the preconcentrator and
## Sensitivity enhancement by on-line preconcentration and in-capillary derivatization for the electrophoretic determination of amino acids This study describes an application of on-line preconcentration by large-volume stacking in combination with in-capillary derivatization for enhancing spectro
