基于TXIB的卷烟搭口胶涂胶量测定方法

TXIB-based method to quantify seam glue in cigarette tobacco rod

摘要

摘要: 为准确测定卷烟搭口胶的涂胶量，基于搭口胶中含有的2，2，4-三甲基-1，3-戊二醇双异丁酸酯（TXIB）增塑剂，通过优化实验条件，建立了测定卷烟搭口胶和烟支卷烟纸搭口涂胶中TXIB的气相色谱质谱联用（GC/MS）方法。结果表明：①卷烟搭口胶中TXIB测定方法的相对标准偏差（RSD）为1.8%，检出限和定量限分别为0.75和2.50 μg/mL，回收率为95.3%~103.1%；②烟支卷烟纸搭口涂胶中TXIB测定方法的RSD为3.1%，检出限和定量限分别为0.26和0.86 μg/mL，回收率为95.2%~105.1%；③该方法具有精密度好、检出限低，准确度高的特点，适用于卷烟搭口胶涂胶量的测定。

Abstract: In order to accurately determine the amount of seam glue in cigarette tobacco rod, specifically for the seam glue containing 2, 2, 4-trimethyl-1, 3-pentanediol diisobutyrate (TXIB) plasticizer, a gas chromatography mass spectrometry (GC/MS) method to measure the TXIB in unused seam glue and in cigarette rod applied seam glue was established. The results showed that: 1) The relative standard deviation (RSD) of the method for unused seam glue was 1.8% with the detection limit and quantitative limit of 0.75 and 2.50 μg/mL and the recoveries of 95.3%-103.1% respectively. 2) The RSD of method for applied seam glue on cigarette rod was 3.1% with the detection limit and quantitative limit of 0.26 and 0.86 μg/mL and the recoveries of 95.2%-105.1%. 3) This method featured a high precision, low detection limit and high accuracy, it was therefore considered suitable for determining the amount of seam glue in cigarette tobacco rod.
