“…In the determination of manganese in gasoline, Jones (105') used an iron rod as a convenient conipensative reference to serve in place of an internal standard. In the course of a year's experience, x-ray emission spectrography as a routine method was found to give results as reliable as the ASTM methods for sulfur and chlorine in petroleum liquids (216). The much shorter time (5 minutes for each element) contributed to a marked reduction of analytical costs and to improved refinery control.…”

1960. One may hope that the appearance of these books wdll help to stabilize, with consideration for the analytical chemist, the confused and proliferating nomenclature in the field under review. SCATTERING While x-ray methods were coming of age in analytical chemistry, it sufficed to know that atoms do scatter x-rays, and that the importance of this scattering increases relative to photoelectric absorption as the atomic number decreases.

“…If the matrix remains reasonably constant, a linear calibration equation applies. However, if the hydrogen-to-carbon ratio of the matrix varies greatly, errors of up to several per cent can result and various corrections must be applied (9,15). An internal standard method or a dilution method often can be used for the more difficult cases.…”

b New automated x-ray methods for determining elements in organic materials, including petroleum and petrochemicals, use bath x-ray emission and scatter methods. Methods for matrix effect and background corrections suitable fot automated analyses were investigated in detail. When possible, correction methods were based only on x-ray data, and more generalized methods capable of simplification for less complex analyses were developed. Specific analytical applications illustrate the utility of the direct and ashing methods for determining vanadium and nickel and direct methods for determining sulfur, carbon, and hydrogen. Direct-reading analyses for some of the more routine determinations were achieved. The use of the new correction methods and techniques speeds analyses and requires much less operator attention for both routine and special analyses.

The concentration of the chlorine in phosphate ester fire-resistant oils needs to be controlled strictly, because it is crucially related to the corrosion of debug system and it is considered as an important indicator to find the hidden faults. It is confirmed that the chlorine content can be tested accurately and conveniently using energy dispersive X-ray fluorescence (EDXRF) spectrometry, due to many advantageous features of this method, namely, rapid response, high sensitivity and good measure precision. The preparation of standard samples and the optimization of analytical conditions are discussed in this paper; then a series of experiments is performed to verify the accuracy of this method. Test results of the samples with chlorine content more than 10mg•kg -1 show that the precision of the proposed measurement method is above 89%, and its repeatability is above 97%. This work not only can provide a feasible method for the rapid detection of chlorine content in phosphate ester fire-resistant oils, but also gives a promising application in power industry. 1
