## Abstract A single step onโline concentration and separation method for peptides in nonโaqueous capillary electrophoresis was developed. ACN containing 50โmM tetraethylammonium perchlorate was used as the electrophoretic medium; angiotensins IโIV were separated as a result of the differences in t
## Abstract We present a new system for the sensitive analysis of cephalosporins by CE using both onโline SPE and largeโvolume sample stacking (LVSS). Sample volumes of 250โ ฮผL were loaded onto the SPE microcolumn which was then desorbed with 426โ nL of ACN. The SPE elution plug was injected into the
