Table 24: Composition of technical and synthetic PCA mixtures determined by ECNI. Specified and
calculated chlorine content [%] are given as well as calculated molecular weights [g/mol] and relative
abundances of the Ci 0 , C n . Qi and Q3 congeners. Technical PCA mixture with a chlorine content <61 %
are marked with a grey shading.
