IP 610: Determination of sulfur, vanadium, nickel, iron, calcium, zinc and phosphorous in residual fuel oil by wavelength dispersive x-ray fluorescence spectrometry

Overview:

This standard specifies a procedure for the determination of sulfur, vanadium nickel, iron, calcium, zinc and phosphorous by wavelength dispersive x-ray fluorescence spectrometry. The concentration ranges that this method covers are shown below:

Element              Range mg/kg

Phosphorus        5 to 50
Sulfur                   0,1 to 3,8 % (m/m)
Vanadium           5 to 400
Nickel                  3 to 100
Iron                      8 to 300
Calcium              8 to 100
Zinc                     3 to 100

For the purposes of this standard, the expressions ‘% (m/m)’ and ‘% (V/V)’ are used to represent the mass and volume fractions respectively.
