Study, Develop, and Improve Procedures and Standardize Instruments for Methods of Chemical Analysis Applicable to the Manufacture of Small-arms Weapons and Components General Operating Accuracies in Fluorescent X-Ray Spectroscopy

摘要

Various types of random and systematic error were studied. Techniques developed for minimizing random error were based upon statistical methods and electrical or mechanical averaging. Techniques used for minimizing systematic error involved either proper choice of apparatus and operating parameters to reduce bias, or calibration to compensate for it.nTechniques compared with respect to precision of measurements and time required for quantitative analysis were (a) working curve method;(b)ratio method;and (c)two-standard method.
