Sulphonated phthalocyanine dyes may be prepared either by direct sulphonation or by mixed condensation methods. Both syntheses will produce mixtures of products. Such mixtures may be analysed by capillary electrophoresis to identify the various degrees of substitution and to indicate the approximate composition of the mixtures.
