Analysis and differentiation of paper samples by capillary electrophoresis and multivariate analysis

This work reports an investigation for the analysis of different paper samples using CEwith laser-induced detection. Papers from four different manufactures (white-copy paper)and four different paper sources (white and recycled-copy papers, adhesive yellow papernotes and restaurant serviettes) were...
