## Abstract A simple isotachophoretic (ITP) preconcentration column for subsequent online capillary zone electrophoresis is described, and its use for enhancing detectability in capillary zone electrophoresis (CZE) is evaluated. Sample preconcentration using ITP is shown to enhance detectability in
The use of an on-line adsorption preconcentrator coupled with capillary zone electrophoresis/nanoelectrospray mass spectrometry (PC/CZE/nESMS) is described for the analysis of peptides and protein digests. The investigation was focused on the production of disposable preconcentrators made of large p
