摘要：

Quantitative analysis of organic materials by ToF-SIMS is intrinsically difficult because of their tendency to decompose under ion irradiation. In this study, we applied principal component analysis (PCA) as a means of compensation for the spectral degradation caused by this decomposition and thus improve the accuracy of the quantitative analysis, using as models two organic additives of quite different composition and vulnerability to decomposition under ion irradiation, in polystyrene. This enables the extraction of a principal component related to their content that is independent of the decomposition. The effectiveness of this approach in quantitative analysis of organic additives content in polymers without loss in accuracy due to spectral degradation will be discussed. (C) 2008 Elsevier B. V.
