In　this　paper,　an　ECL　detection　system　equipped　with　an　electrically　heating　controlled　cylindrical　microelectrode　(HME)　was　used　to　study　the　ECL　behavior　of　lucigenin.　The　ECL　intensity　of　lucigenin　would　be　increased　at　elevated　electrode　temperature　but　the　noise　had　not　been　increased.　It　was　found　that　ECL　intensity　at　higher　temperature　of　electrode　surface　(80　degrees　C)　was　more　than　two　magnitudes　stronger　than　that　at　the　room　temperature　(22　degrees　C).　The　detection　limit　for　ECL　of　lucigenin　on　a　HME　is　much　lower　than　that　on　an　electrode　without　heating,　based　on　which,　it　is　possible　to　establish　a　more　sensitive　method　for　measurement　of　ECL　by　using　a　HME.　The　heating　of　electrode　has　been　used　to　renew　the　electrode,　which　avoid　the　tedious　work　for　refreshing　the　electrode　surface.　The　reproducibility　of　lucigenin　ECL　system　at　HME　is　satisfactory.　(c)　2006　Elsevier　B.V.All　rights　reserved.
