一般描述
Application: This special purpose and specially tested capillary GC column is designed for the analysis of polycyclic aromatic hydrocarbons (PAHs). It incorporates an ionic liquid stationary phase. Each column is individually tested to ensure resolution of several key sets (phenanthrene/anthracene, benzo[a]anthracene/chrysene/triphenylene, and benzo [b]fluoranthene/benzo[k]fluoranthene/benzo[j]fluoranthene).
USP Code: None
Phase: Non-bonded; 1,12-Di(tripropylphosphonium)dodecane bis(trifluoromethanesulfonyl)imide
Temp. Limits: Subambient to 300 °C (isothermal or programmed)

Retention behavior of alkyl-substituted polycyclic aromatic sulfur heterocycle isomers in gas chromatography on stationary phases of different selectivity
This study investigates the retention behavior of polycyclic aromatic sulfur heterocycles (PASHs) using gas chromatography with different stationary phases, including ionic liquids (ILs). The IL phase demonstrated unique selectivity and correlation with PASH geometry. (Wilson, Lee, et al, 2017)

Retention behavior of isomeric polycyclic aromatic sulfur heterocycles in gas chromatography on stationary phases of different selectivity
The research evaluates the gas chromatographic retention indices of alkyl-substituted PASHs using various stationary phases, including ionic liquids. Results indicate that ILs offer distinct selectivity and thermal stability, enhancing the separation of complex mixtures.

Ultra-high thermal stability perarylated ionic liquids as gas chromatographic stationary phases for the selective separation of polyaromatic hydrocarbons and polychlorinated biphenyls
This article explores the use of perarylated ionic liquids as stationary phases in gas chromatography for separating polycyclic aromatic hydrocarbons and polychlorinated biphenyls. The ILs exhibit high thermal stability and unique selectivity, improving the resolution of challenging analytes.
