N2 - It is shown that the group and individual composition of A-92 motor gasoline can be determined on a PTMSP025 capillary column with a poly(1-trimethylsilyl-1-propyne) (PTMSP) stationary phase. It was found that the PTMSP column is characterized by the order of elution similar to that for capillary columns with porous organic polymers. Hydrocarbons are eluted in groups according to the number of carbon atoms in the molecule. Alkenes are eluted first in the group, and then alkanes are eluted. This order of hydrocarbon retention on the PTMSP025 column allows a more structured pattern of separation compared to the column with the polysiloxane stationary phase. Methyl-tert-butyl ether (MTBE), used as an octane booster, is determined on a PTMSP025 column without an additional sample preparation (concentration) step. The possibility of separating gasoline components using comprehensive two-dimensional chromatography was also demonstrated, where a PTMSP025 column was installed in the first dimension, and a column with dimethylpolysiloxane as a stationary phase in the second.
