A　new　analytical　method,　pressurized　capillary　electrochromatography　with　indirect　amperometric　detection,　has　been　developed　for　the　determination　of　some　non-electroactive　organophosphorus　pesticides　(OPPs).　When　0.1　mmol　L　-1　of　3,4-dihydroxybenzylamine　(DHBA)　was　added　to　the　mobile　phase　containing　50%　v/v　of　ACN　and　50%　v/v　of　MES　buffer　(10　mmol　L-1,　pH　5.5),　and　+0.9　V　(vs.　Ag/AgCl)　of　working　potential　were　used,　maximal　signal　levels　of　analytes　could　be　achieved.　A　separation　voltage　of　+10　kV,　a　column　pressure　of　7.0　MPa　and　a　pump　flow　rate　of　0.05　mL　min-1　were　selected　as　the　other　optimal　conditions　for　separation　of　six　OPPs,　namely,　dimethoate,　methyl　parathion,　ethyl　parathion,　chlorpyrifos,　chlorpyrifos-methyl,　trichlorfon.　The　OPPs　could　be　separated　within　15　min　and　determined　with　the　detection　limits　ranging　from　0.008　to　0.2　mg/kg.　Combining　with　a　solid　phase　extraction　procedure,　mean　recoveries　between　78.9　and　87.2%　for　vegetable　samples　and　from　81.4　to　98.6%　for　fruit　samples　were　obtained.　©　2010　The　Royal　Society　of　Chemistry.
