The enantiomeric resolution of <jats:italic>o,p<\/jats:italic>\u2010DDT and <jats:italic>o,p<\/jats:italic>\u2010DDD has been achieved on Chiralpak AD\u2010R, Chiralcel OD\u2010R, and Chiralcel OJ\u2010R chiral stationary phases. The mobile phases used were acetonitrile\u2013water (50:50 [v\/v]) and acetonitrile\u20102\u2010propanol (50:50 [v\/v]) at a flow rate of 1.0 mL\/min. For both pesticides detection was done at 220 nm.
