Comparison of Methods of Standardization of X-Ray Data
Various methods of standardizing X-ray emission calibration data for day-to-day variations have been studied. The method of using an external standard either as a ratio or slope correction is clearly the best approach. The use of internal standard lines can be as effective, but this method can be susceptible to large errors over extended periods of time. The parallel-curve shift correction method has limited application. Finally, data are presented which show that the analytical precision of a fully automated X-ray spectrograph approaches the statistical accuracy of the X-ray measurements.
