| Abstract: | A new method for quantitative phase analysis without standards (QPAWS) is discussed on the basis of known mass absorption coefficient of each phase. The least-squares regression method has been used for QPAWS analysis. A new deduction and a new formula are presented in this paper. Experimental verification of the method with three-phases of artificial mixtures gave satisfactory results. |
