New systems have been developed for the measurement of effective interfacial area, a, by the chemical method which allow the use of hydrocarbon solvents, such as toluene, xylene, etc; polar solvents, such as benzyl alcohol, cyclohexanol, etc; and highly viscous solvents, such as diethylene glycol, p
