Abstract

A comparison study of XRF and <TEX>$^{31}P$</TEX>-NMR method for the analysis of phosphorous in lubricating oil has been described. Pure oil and water were used for the observation of matrices effect variation by different analytical methods. Quantitative analysis was carried out by XRF and <TEX>$^{31}P$</TEX>-NMR using real samples. Significant difference is observed from the slopes on the calibration curves by the XRF due to the matrices (water: 124.0, oil: 276.6). While the result obtained from XRF showed a large matrix effect, the slopes obtained from <TEX>$^{31}P$</TEX>-NMR results of two different matrices, however, are in good agreement ranged of <TEX>${\pm}9%$</TEX> (water: 4.9, oil: 5.3).
