## Abstract A dual‐layer ion‐exchange latex‐coated column was prepared and characterised for on‐capillary preconcentration of cations using an open‐tubular ion‐exchange CEC format. After preconcentration, the analyte cations were eluted with a transient isotachophoretic gradient and separated by CE

A laboratory working procedure is described for silanization of glass capillaries with bis(cyanopropyl)tetramethyldisiloxane, prior to coating with XE-60-~-valine-(S)-a-phenylethylamide as chiral stationary phase. GC columns thus prepared exhibit good inertness and no long-term deterioriation of ena
