AB  - The presence of inorganic elements in fuel gas generally accelerates the 
      corrosion and depletion of materials used in the fuel gas industry, and even 
      leads to serious accidents. For identification of existing trace inorganic 
      contaminants in fuel gas in a portable way, a highly efficient gas-liquid 
      sampling collection system based on gas dispersion concentration is introduced in 
      this work. Using the constructed dual path gas-liquid collection setup, inorganic 
      cations and anions were simultaneously collected from real liquefied petroleum 
      gas (LPG) and analyzed by capillary electrophoresis (CE) with indirect UV 
      absorbance detection. The head-column field-amplified sample stacking technique 
      was applied to improve the detection limits to 2-25 ng mL(-1). The developed 
      collection and analytical methods have successfully determined existing inorganic 
      contaminants in a real LPG sample in the range of 4.59-138.69 mug m(-3). The 
      recoveries of cations and anions with spiked LPG samples were between 83.98 and 
      105.63%, and the relative standard deviations (RSDs) were less than 7.19%.
