Notes:
A comparison of X-ray and chemical analyses of phosphorus and sulfur standards of KH2PO4- and (NH4)2SO4-cellulose was performed to determine the range of applicability of a numerical matrix correction technique. Over the range 0.1 — 1.0%, the X-ray technique was accurate to within 8% for phosphorus and 17% for sulfur. At 0.03%, the X-ray values are low by 17% or more. At 3.0% and 10.0%, particle size effects caused the values to be low by more than 17%. X-ray analysis of pure sulfur and (NH4)2SO4 was accurate to within 13% and indicates the validity of the mathematical technique. Application was made to the analysis of wheat and standard reference plant materials.
