摘　　要：为探究影响水基胶中甲醛测定值准确性及平行性的重要因素,采用超高效液相色谱法(UPLC)对不同厂家生产的不同型号卷烟用水基胶样品进行多组平行检测,并进行方差分析及t检验.结果表明:空白值对样品测定有着显著性影响,随空白值的升高,测试结果变得不准确;通过对空白值各组分的进一步分析研究,发现对空白值影响较大的组分是2,4-二硝基苯肼及磷酸;前处理中对空白各组分的控制可以有效降低空白值,提高样品检测结果的准确性和可靠性.To investigate the important factor effecting the accuracy and parallelism of formaldehyde values in water-borne adhesives for cigarette, we use uhra-performance liquid chromatography （UPLC） do muhiple parallel detection and variance analysis and t test for different water-borne adhesives samples from different manufacturers. The results show that the determination of the sample blank value has a significant influence. Rising with the blank value, inaccurate test resuhs happened. For the further analysis of Blank value of each component, we found that the 2,4-dinitrophenylhydrazine and phosphoric acid have greater impact factor. Pretreatment of the components of the blank control can reduce the blank value, and increase sample accuracy and reliability of test results.
