Comparison of carrier gases for the separation and quantification of mineral oil hydrocarbon (MOH) fractions using online coupled high performance liquid chromatography-gas chromatography-flame ionisation detection

This study evaluates hydrogen, helium, and nitrogen as carrier gases in HPLC-GC-FID for MOH analysis in food, showing nitrogen as a suitable and effective alternative despite some peak broadening.
