研究了超高效液相色谱用于卷烟包装纸中甲醛和乙醛含量测定方法。甲醛和乙醛通过2，4-二硝基苯肼衍生化后，以0．5％甲酸水溶液-乙腈（体积比为65：35）为流动相，在Waters BEH Shield RP18（1．7um，2．1mm×50mm）色谱柱上分离，二极管阵列检测器检测，检测波长360nm。甲醛和乙醛在5min内即可完全分离，方法具有较好的重现性和线性关系，相关系数均达到0．9999，加标回收率甲醛为97．9％，乙醛为95．5％；用于卷烟包装纸中甲醛和乙醛的快速测定，结果满意。

An ultra performance liquid chromatographic (UPLC) method for determination of formaldehyde and acetaldehyde in cigarette wrapping paper was studied. The formaldehyde and acetaldehyde were derivatizated with 2,4-dinitrophenylhydrazine, then they were separated by Waters BEH ShieldRP18 column with 0.5% formic acid and acetonitrile (65:35, v/v) as mobile phase and detected with photodiode array detecter (PDA) at 360 nm. The formaldehyde and acetaldehyde were completely separated and detected in 5 min. The method has good repeatability and linearity. All the correlation coefficients are above 0. 9999. Their recoveries were 97.9% and 95.5% respectively. The method was satisfied with the results by rapid determination of formaldehyde and acetaldehyde in cigarette wrapping paper.
