The mixed stationary phases enhanced sorption efficiency for different classes of aromatic compounds and their sulfur analogs.
Sorption enthalpy (∆H) and entropy (∆S) were analyzed for various polymer mixtures, revealing unique characteristics.
Gas chromatography was utilized to assess the performance of different blends of polydimethylsiloxane and polyethylene glycol in separating compounds.
These findings highlight the potential for developing more effective stationary phases tailored for specific aromatic compounds.
