Assessment of the sequential principal component analysis chemometric tool to identify the soluble atmospheric pollutants in rainwater
(Springer, 2011)
In this study a new method of principal component (PC) analysis, sequential PC analysis (SPCA), is proposed and assessed on real samples. The aim was to identify the atmospheric emission sources of soluble compounds in ...
