A mathematical model for assessment of uncertainties in the determination of phenol in mainstream smoke of cigarette by high performance liquid chromatngraphy ( HPLC) was established. The sources of these uncertainties were analyzed and assessed one by one, finally concluding the exact uncertainties in the detection of phenol in mainstream smoke of cigarette.%建立高效液相色谱(HPLC)法测定卷烟主流烟气中苯酚含量的不确定度评定的数学模型,通过对测量过程中的不确定度来源进行i逐项分析与评定,得出了HPLC法测定卷烟主流烟气中苯酚含量的不确定度结果.
