System for calculating the linear temperature‐programmed retention indices of polycyclic aromatic compounds

Abstract

SummaryTheoretical procedures have been used to predict linear temperature-programmed retention indices for polycyclic aromatic compounds. It is possible to calculate such indices for polycyclic aromatic compounds in some practical situations in which the compounds cannot be eluted during a simple linear temperature program. The theory has been tested for a number of polycyclic aromatic hydrocarbon (PAHs) in single-and multi-plateau temperature-programmed gas chromatography with SE-52 as the stationary phase. This method will extend the applicability of linear retention indices for the identification of the isomers of polycyclic aromatic compounds.

“…High-performance liquid chromatography (HPLC) and high-resolution gas chromatography (HRGC) have been applied to the separation of PAHs [17][18][19]. Retention index have been used to identify PAHs and confirmed by HRGC-FID/MS for the positive identification of resolved components [20][21][22][23][24][25][26]. The burning of the biomass is the major source of emission of particulate material (PM), of the order of 104 Tg/year [27].…”
