Traditional method used for determining sulfer content in heavy oil has some shortcomings

such as long analysing duration

low analysing efficiency

complex operation

and bad repeatability etc..Using X-ray fluoresence spectrometer to determine sulfer content in heavy oil

and comparing the measured results with that of Coulomb's tittrimetric method

the deviation to be only 0.004%.it is within the allowable error stipulated in National Standard GB/T 214-1996.The test shows that the X-ray fluoresence method has advantages as convenient operation

fast speed

and good repeatabilibity etc..
