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

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.
