Multielement Analysis of Crude Oils Using Inductively Coupled Plasma-Atomic Emission Spectrometry

CODEN: JAIOAD

Abstract

In addition to the sulfur determined as a part of the crude assay, it is important to know the concentration levels of a number trace elements in crude oils. A method is described for the multielement metal analysis of crude oils using inductively coupled plasma atomic emission spectrometry (ICP-AES). The samples are diluted with an organic solvent before measurements. Metallo-organic compounds dissolved in organic solvents are used as calibration standards. Precision of analysis was established based on an ASTM interlaboratory study. NIST Standard Reference Materials of crude oils where available were analyzed to estimate the bias of the new test method.
