Figure 22: Principal component plots of the factor analysis of the congener group composition of sPCA 
(A) and mPCA (B) in technical mixtures from European producers and sediments from the 
North and Baltic Sea ( years 2001-2002). Results were obtained by CH4/CH2CI2-NICI-MS. Two 
groups with related patterns are marked for sPCAs 120
