Simultaneous determination of 23 ester compounds in cigarette water-borne adhesives by liquid-liquid extraction and gas chromatography-mass spectrometry

Abstract

A method of gas chromatography-mass spectrometry (GC-MS) with liquid-liquid extraction has been developed for the simultaneous determination of 23 ester compounds including acetate esters, acrylic esters, metacrylic acid esters and phthalate acid esters in cigarette water-borne adhesives. After dispersed in water, the sample was extracted by n-hexane solution containing phenyl ethyl propionate as internal standard substance. Then, the solution was centrifuged and filtrated through a 0.45 microm organic membrane filter. Finally, the solution was separated on a DB-WAXETR column (60 m x 0.25 mm x 0.25 microm), and detected with MS in selected ion monitoring mode, and quantified by internal standard method. The results showed a good linear correlation in the range of 0.4-50.0 mg/L. The recoveries of the ester compounds spiked in the sample were 81.8%-109.1%, and the relative standard deviations (RSDs, n = 5) were less than 4%. The limits of detection (LODs) and limits of quantification (LOQs were in the ranges of 0.02-0.76 mg/kg and 0.04-2.52 mg/kg, respectively. The method is simple, time-saving, and has high sensitivity and good reproducibility. It can be applied to the determination of the 23 ester compounds in cigarette water-borne adhesives.

Multifunctional MgO/HKUST-1 Composite for Capture, Catalysis, and Cyclic Cataluminescence Detection of Esters All-In-One to Rapidly Identify Scented Products

“…The catalytic materials have an important effect on CTL performance . Esters, alkenes, alcohols, aldehydes, ethers, and ketones are abundant in scented products. , They were used as reagents to trigger the CTL reaction on the surface of MgO/HKUST-1. As shown in Figure S5, the MgO/HKUST-1 demonstrates a high selectivity toward esters.…”

Simultaneous determination of seven acrylates in food contact paper products by GC/MS and modified QuEChERS

“…To date, literature reports of acrylates have been mainly focused on the detection of residual acrylate monomers in plastics or in the air, and the detection methods mainly included gas chromatography (GC), liquid chromatography (LC), and gas chromatography with mass spectrometry (GC/ MS). [7][8][9] A few reports mentioned the detection of acrylate compounds in food contact paper products. For example, Sun et al established the detection of migration amounts of ve acrylates in plastic food-contacting materials by solid-phase microextraction and GC/MS.…”
