In this work, an on-line preconcentration method of field-enhanced sample injection (FESI) was implemented in the determination of four β -agoinsts terbutaline (TER), procaterol (PRO), formoterol (FOR) and bambuterol (BAM) by capillary electrophoresis coupled with capacitively coupled contactless co...
