The present paper investigates the influence of solvent purity on the test of three-dimensional fluorescence spectral determines the process of its pre purification. and studies the influence of the concentrations on the three-dimensional fluorescence characteristic indexes such as the characteristic peaks position. fluorescence intensity (F), and ratio (R) of fluorescence intensity when the phenomena of fluorescence quenching won't appear, The result show,; that the concentration. affects the value F and value R largely but its effect on the relative peak intensity (R(s)) is relatively small. Different crude oils has different value R(s), According to those characteristics. this paper presents that the value R(s) can be used as it new characteristic index for identification of crude oil. This, conclusion was confirmed by testing many crude oils stably and reliably from different areas with their concentrations at 5 mg . L(-1). This method can be applied to identify most crude oils preliminary and further accurate analysis call be carried out together with other index.
