E85 is a mixture of ethanol and gasoline where the ethanol concentration can range from 70 to 85 vol%. The increased peak capacity and selectivity generated by GC\u00d7GC analysis allowed the alcohols to be fully resolved from the gasoline hydrocarbons. GC\u00d7GC analysis was compared to the performance obtained with the standard analytical method for determining ethanol in fuel ethanol (ASTM D5501) and the standard method for determining oxygenate concentrations in gasoline (ASTM D4815). The GC\u00d7GC analysis required 14 min while the combined ASTM D5501 and ASTM D4815 analyses required more than 60 min. The ethanol concentration obtained by GC\u00d7GC was in excellent agreement with the value obtained by the D5501 method. Poorer agreement was observed between the GC\u00d7GC and D4815 concentrations for the other alcohols present in E85. In all cases, the differences could be attributed to deficiencies in the D4815 method that led to coelutions between the alcohols and gasoline hydrocarbons.<\/jats:p>","DOI":"10.1002\/jssc.200800258","type":"journal-article","created":{"date-parts":[[2008,9,19]],"date-time":"2008-09-19T11:27:58Z","timestamp":1221823678000},"page":"3337-3346","source":"Crossref","is-referenced-by-count":19,"title":["Comprehensive two\u2010dimensional gas chromatography analysis of high\u2010ethanol containing motor fuels"],"prefix":"10.1002","volume":"31","author":[{"given":"John V.","family":"Seeley","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elise M.","family":"Libby","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stacy K.","family":"Seeley","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James D.","family":"McCurry","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,10,16]]},"reference":[{"key":"e_1_2_1_2_2","unstructured":"ASTM Standard D 5798 Standard Specification for Fuel Ethanol (Ed75\u2010Ed85) for Automotive Spark\u2010Ignition Engines ASTM International West Conshohocken PA USA 2007."},{"key":"e_1_2_1_3_2","unstructured":"ASTM Standard D 5501 Standard Test Method for Determination of Ethanol Content of Denatured Fuel Ethanol by Gas Chromatography ASTM International West Conshohocken PA USA 2004."},{"key":"e_1_2_1_4_2","unstructured":"ASTM D02.04 Section L Minutes Study Group on D5501 ASTM International West Conshohocken PA USA 2007."},{"key":"e_1_2_1_5_2","unstructured":"ASTM Standard D 4815 Standard Test Method for Determination of MTBE ETBE TAME DIPE tertiary\u2010Amyl Alcohol and C1to C4Alcohols in Gasoline by Gas Chromatography ASTM International West Conshohocken PA USA 2004."},{"key":"e_1_2_1_6_2","unstructured":"ASTM D02.04 Section L Minutes Study Group on Oxygenates ASTM International West Conshohocken PA USA 2004."},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-4168(19980101)21:1<47::AID-JHRC47>3.0.CO;2-5"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-4168(19981101)21:11<620::AID-JHRC620>3.0.CO;2-#"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac980164m"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-4168(19990101)22:1<3::AID-JHRC3>3.0.CO;2-U"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-4168(19990401)22:4<195::AID-JHRC195>3.0.CO;2-7"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2003.07.016"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2003.08.097"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.200390079"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.200301649"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2005.06.015"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-4168(20000301)23:3<197::AID-JHRC197>3.0.CO;2-R"},{"key":"e_1_2_1_18_2","first-page":"24","volume":"38","author":"Seeley J.
