摘要

摘要对现有的卷烟烟气冷凝水含水量测定方法进行了改进,采用自动终点停止卡尔费歇尔滴定仪。因此,整个过程变得更快(滴定时间少于2分钟),更容易(滴定过程中不需要监督)和更好的重现性(测定水量的变异系数为2.5%)。在这三个标准中,自动卡尔费歇尔法优于作为比较方法的气相色谱法。

The Determination of the Water Content in Cigarette Smoke Condensate Using a Karl Fischer Titrator / Wasserbestimmung im Rauchkondensat nach Karl Fischer mit einer halbautomatischen Apparatur
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.
