Although many papers have been published describing methods for the inorganic analysis of petroleum no book has previously appeared devoted exclusively to this subject. The purpose of this work is to provide a laboratory handbook for industrial analysts of various degrees of professional training covering the determination of those elements commonly occurring in various types of petroleum products.The procedures represent, from the author's point of view, a reasonable compromise among the usual conflicting interests of speed, accuracy, and cost, and emphasize manufacturing rather than research applications.
