The paper is divided into two parts. The first section presents a review of three basic methods of X-ray spectrochemical analysis, including the internal standard method, the absolute intensity method, and the ratio method. The applications and limitations of each are discussed briefly. The second section presents the ratio method at length. Included are the methods of acquiring standards, sample preparation, curve plotting, and a discussion of the factors contributing to the precision of the analysis. Various analytical curves are presented and discussed and the sensitivity for minor constituents is shown.
