a Separation resolution of nonane isomers on Zr-TCPE coated column with additional heating at 250 °C for 4, 6, and 12 h. b Gas chromatograms of Zr-TCPE, Zr-TCPE-L1, Zr-TCPE-L2, and Zr-TCPE-DLI coated columns for the separation of ethyltoluene isomers. The numbers on the left represent the elution time of the first peak. c Separation resolution of octane isomers and the mixture of 1-heptene, n-heptane, and cycloheptane on Zr-TCPE, Zr-TCPE-L1, Zr-TCPE-L2, and Zr-TCPE-DLI coated columns. 2,4-C8, 3-C8, and n-C8 represent 2,4-dimethylhexane, 3-methylheptane, and n-octane, respectively. The scale was normalized to Zr-TCPE-DLI. d Separation resolution for 3-methylheptane and n-octane isomers on Zr-TCPE, Zr-TCPE-H, Zr-TCPE-L1, Zr-TCPE-L1-H, Zr-TCPE-L2, Zr-TCPE-L2-H, Zr-TCPE-DLI, and Zr-TCPE-DLI-H coated columns. e Gas chromatograms of Zr-TCPE-H, Zr-TCPE-L1-H, Zr-TCPE-L2-H, and Zr-TCPE-DLI-H coated columns for the separation of ethyltoluene isomers. f Separation resolution of octane isomers and the mixture of 1-heptene, n-heptane, and cycloheptane on Zr-TCPE-H, Zr-TCPE-L1-H, Zr-TCPE-L2-H, and Zr-TCPE-DLI-H coated columns. The scale was normalized to Zr-TCPE-DLI.
