气相色谱法测试卷烟烟气冷凝物中薄荷醇国际标准的研究

Results of Collaborative Tests on International Standard:Cigarettes-Determination of Menthol in Smoke Condensates-Gas Chromatographic Method

摘要: 介绍了国内6家实验室研究国际标准ISO 13110:2012《卷烟烟气冷凝物中薄荷醇的测定气相色谱法》精密度、萃取时间对测试结果的影响及其适用性等。结果表明:①萃取20与60 min对薄荷醇测试结果无显著影响;②该研究得到的精密度与ISO 13110:2012处于同一数量级,重复性限(r)与薄荷醇含量的比值小于10%,再现性限(R)与薄荷醇含量的比值为25%~45%。ISO 13110:2012规定的气相色谱法适用于国产薄荷型卷烟的测定。

Abstract: Collaborative test on the ISO 13110:2012 "Cigarettes-Determination of menthol in smoke condensates-Gas chromatographic method" was conducted in six domestic laboratories. The results showed that:1) Extracting for 20 or 60 minutes had no significant influence on the determining results of menthol;2) The precision of these studies was in the same order of magnitude as those described in ISO 13110:2012,the ratio of repeatability limit (r) to the mean of menthol contents was less than 10% and the ratio of reproducibility limit (R) to the mean of menthol contents ranged from 25% to 45%. The GC method described in ISO 13110:2012 is suitable for domestic menthol cigarettes.
