Abstract
Abstract The current method of determination of the water content of cigarette smoke condensate was improved by using a Karl Fischer titrator with automatic end-point stop. The overall procedure thus becomes faster (the titration time is less than 2 minutes), easier (no supervision is needed during the titration) and better reproducible (coefficient of variation 2.5 % on the amount of water determined). In these three criterions, the automated Karl Fischer method is superior to a gas-chromatographic procedure having served as a method of comparison.
