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
## Abstract A two‐leveled, two cross PDMS‐based interface for on‐line coupling of SPE with CE‐MS was proposed. In this interface, the SPE column and the CE separation column were positioned orthogonally and two crosses were fabricated on the interface. With the two cross design, the operation of SP
