Binary mobile phases with chloroform, dichloromethane, or tetrahydrofuran as strong solvent and methanol or acetonitrile as weak solvent were tested. The volume fraction of strong solvent in the binary phases was between 0.3 and 0.8. Curves of eluotropic strength versus volume fraction of strong solvents showed similar trends to previously published results for saturated homologues. Correlation coefficients of the plots of eluotropic strength values for saturated versus unsaturated FAMEs were close to 1.0. Therefore these similarities validate the model of eluotropic strength previously established with saturated FAMEs as relevant for unsaturated FAMEs. The separation factors between <jats:italic>cis<\/jats:italic> and <jats:italic>trans<\/jats:italic> homologues always showed elution of the <jats:italic>cis<\/jats:italic> before the <jats:italic>trans<\/jats:italic> homologue. The difference in retention is due primarily to the geometry of the molecule. The retention is lowered more by the addition of a first carbon double bond than by the addition of a second one, independently of the mobile phase composition.<\/jats:p>","DOI":"10.1002\/jssc.200301622","type":"journal-article","created":{"date-parts":[[2004,1,16]],"date-time":"2004-01-16T10:49:20Z","timestamp":1074250160000},"page":"41-46","source":"Crossref","is-referenced-by-count":9,"title":["Retention behaviour of unsaturated fatty acid methyl esters on porous graphitic carbon"],"prefix":"10.1002","volume":"27","author":[{"given":"Karen","family":"Gaudin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Chaminade","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arlette","family":"Baillet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,1,13]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(00)82246-3"},{"key":"e_1_2_1_3_2","first-page":"41","volume":"3","author":"Kaur B.","year":"1989","journal-title":"LC\u2010GC Int."},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(02)01123-8"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1080\/01483919108049334"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(00)91416-X"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9673(94)85241-3"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(01)83336-7"},{"key":"e_1_2_1_9_2","first-page":"73","volume":"37","author":"Knox J.H.","year":"1997","journal-title":"Adv.
