A　strategy　on　amperometric　detection　for　CZE　of　phenol　carbamates　as　model　analytes　with　a　facile　in-line　thermal　hydrolysis　was　presented,　in　which　a　thermal　hydrolysis,　subsequent　CZE　separation　and　final　column-end　amperometric　detection　were　accomplished　in　an　intact　capillary.　Key　parameters　of　hydrolysis　dynamics　of　carbamates　and　electrochemical　detection　of　the　hydrolysates　were　studied,　as　well　as　electrophoretic　conditions.　Under　the　optimal　conditions,　the　capillary　was　utilized　as　chambers　for　in situ　hydrolysis,　CZE　separation,　and　electrochemical　detection.　The　successive　separation　of　hydrolysates　of　five　carbamates　(propoxur,　carbofuran,　3-OH-carbofuran,　carbaryl　and　bendiocarb)　were　achieved　within　17 min.　Applied　to　vegetable　samples,　the　recoveries　of　carbamates　fortified　at　0.02　and　0.05　mg/kg　were　ranging　in　88–107.2　and　86.3–107.3%,　respectively.　The　success　in　the　implementation　of　such　a　scheme　resulted　in　a　simple　instrument　as　compared　with　those　current　analytical　methods　with　post-column　derivization　or　pre-column　hydrolysis,　or　online　enrichment　in　chip,　respectively.　This　protocol　might　possess　a　potential　utility　for　the　sensitive　amperometric　detection　of　phenol　carbamates.　©　2019　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
