A previous paper of this series reported the initial results of a study designed to investigate the application of SEM microanalysis to paper. Fifty-four different papers, primarily writing papers, were analyzed; the wide variation of elemental content confirmed the forensic usefulness of such an analysis. In addition, the compositional uniformity of two common writing papers was examined more closely; even for very small test areas ( ~ 0.06 mm²), the apparent compositional variations across the sheet were much less than those between different papers. This paper reports the results of a continuation of the previous study in which attention is now focused on the compositional variations among identically labeled sheets of paper.
