    1. Scope

    This method is for determining total aromatics in Molex n-paraffin products. The method determines an average amount of naphthalenes and alkylbenzenes that may be present, provided the concentration of the alkylbenzenes is at least ten times greater than the naphthalenes. In practice, this condition is satisfied for the specified applications. Other samples with similar compositions may also be suitable for this analysis. The lower limit of detection is 0.0003 mass-%.
