The carbon black content of a material sample including organic materials and iron oxide is determined by a sequence of steps including chloroform dissolution of polymers and hydrochloric acid dissolution of iron oxide with interspersed steps of centrifuge separation. The process is particularly useful for determining the carbon black content of copier toner materials including monocomponent toners.
