March 1990

This CORESTA Recommended Method (CRM) specifies the use of the Karl Fischer method for the determination of water in cigarette smoke condensate. The smoke condensate from the mainstream smoke is dissolved in a solvent. The water content of an aliquot of the solution is determined by titration with standardised Karl Fischer reagent.
