Abstract | Sets of thin polymer films were developed to serve as standards for XRF analysis of the following 18 elements in aerosol particle samples: Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ge, As, Rb, Sr, Zr, Cd, Sb, Ba, and Pb. Each film contains a pair of elements having non-interfering x-rays, and each set consists of 9 such films. Element concentrations were replicated to a precision of about 1%. To determine absolute amounts, the films were analyzed by 8 laboratories. Accuracies of concentrations of 15 of the elements ranged from 2 to 9%. Stability for films stored at -18 deg C and +22 deg C was better than 1% y sub minus 1. (Copyright (c) 1988 by Marcel Dekker, Inc.) |
