UOP 699 – Sodium in Liquefied Petroleum Gas by ICP-OES or AAS
This method is for determining the concentration of sodium (Na) as dissolved and suspended sodium compounds in liquefied petroleum gas (LPG) in the range of 0.1 to 10 mg/kg (mass-ppm) sodium. After sample preparation, either Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES, or ICP) or Atomic Adsorption Spectroscopy (AAS) can be utilized to determine the sodium concentration.
