N2 - This study investigated the separation selectivity for C1–C10 aromatic and aliphatic hydrocarbons (both saturated and unsaturated) and methanol contained as contaminants in n-butane (>99% pure). It was shown that a 30 m × 0.32 mm porous-layer capillary column with a 1.55 μm poly(1-trimethylsilyl-1-propyne) film (PTMSP032) provides a significantly higher peak resolution for C1–C2 hydrocarbons and structural isomers (o-, m-, and p-) of xylene, than a commercial 30 m × 0.32 mm column with a 10 μm polydivinylbenzene layer (Rt-Q-BOND). A PTMSP032-based GC method was developed, which avoids the need for an extra sample-preparation step and assures the rapid and accurate identification of hydrocarbon and methanol impurities in an n-butane gas sample. The FID detection limit was evaluated to range from 3.21 × 10–12 to 6.68 × 10–12 g/s for hydrocarbons and to be 2.78×10–11 g/s for methanol. The repeatability, determined as the root-mean-square deviation (RMSD) of peak area, amounted to 4.20% for hydrocarbons, and varied from 4.96 to 0.29% for methanol in concentrations of 0.06×10–3 to 1.01×10–2 mg/mL, respectively.
