Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. investigated the retention performance of various Al2O3 for low-carbon hydrocarbons. Using γ - Al2O3 as the stationary phase and 2% Na2SO4 aqueous solution for deactivation, a 0.32 mm × 50 m Al2O3PLOT (porous layer open tubular) quartz capillary chromatography column was successfully developed. This column has strong separation ability for C1~C8 low-carbon hydrocarbons, with good selectivity, column inertness, and high column capacity. A chromatographic analysis method for liquefied gas has been established, with chromatographic conditions: vaporization at 160 ℃, detection at 180 ℃, column temperature at 80 ℃, holding for 4 minutes, raising by 8 ℃/min, final temperature at 160 ℃, holding for 11 minutes; FID detection; The front pressure of the carrier gas (N2) column is 0.042 MPa, the split ratio is about 180:1, the tail blowing is 25 mL/min, the air flow rate is 350 mL/min, and the hydrogen flow rate is 35 mL/min; The injection volume is 50 μ L.
