This standard specifies the microwave ashing inductively coupled plasma emission spectrometry method for the determination of sodium, magnesium, calcium, iron, vanadium, nickel, and copper in crude oil. This standard is applicable to the determination of sodium, magnesium, calcium, iron, vanadium, nickel, and copper in crude oil. The lower limit of determination of sodium, magnesium, calcium, iron, vanadium, nickel, and copper is: sodium 0.2 mg/kg, magnesium 0.02 mg/kg. , calcium 0.02mg/kg, iron 0.02mg/kg, vanadium 0.05mg/kg, nickel 0.05mg/kg, copper 0.05mg/kg.
