Problems solved by technology

However, the conventional DLLME method also has certain limitations. This method is generally more suitable for the detection of water samples. When it is applied to samples with high ethanol content and complex organic matter, such as flavors and fragrances and tobacco additives, the matrix effect will not be possible. The avoidance is more obvious, and the repeatability and recovery rate also have room for improvement

Embodiment 1

[0077] 1. Preparation of standard solution

[0078] Weigh the standard products of musk xylene and sesamol respectively, add absolute ethanol to constant volume, and make a mixed standard stock solution. The concentrations of musk xylene and sesamol in the mixed standard stock solution are both 1-100 μg / mL. Simultaneously, pipette the isotopes of musk xylene and the isotope of sesamol of a certain volume respectively, specifically deuterated musk xylene and deuterated sesamol, add absolute ethanol to constant volume, be made into internal standard solution, in the internal standard solution, two The concentrations of isotopes of toluene musk and sesamol are 10-1000 μg / mL.

[0079] Accurately pipette different volumes of mixed standard stock solutions, place them in multiple 100mL volumetric flasks, then accurately add a certain volume of internal standard solution, and dilute with absolute ethanol to prepare a series of mixed standard solutions. The concentration of the prep...

Embodiment 2

[0091] 1. Preparation of standard solution

[0092] Weigh the standard products of musk xylene and sesamol respectively, add absolute ethanol to constant volume, and make a mixed standard stock solution. The concentration of xylene musk and sesamol in the mixed standard stock solution was 10 μg / mL. Simultaneously, pipette the isotopes of musk xylene and the isotope of sesamol of a certain volume respectively, specifically deuterated musk xylene and deuterated sesamol, add absolute ethanol to constant volume, be made into internal standard solution, in the internal standard solution, two The concentration of the isotope of toluene musk and the isotope of sesamol was 100 μg / mL.

[0093] Accurately pipette different volumes of mixed standard stock solutions, place them in five 100mL volumetric flasks, then accurately add a certain volume of internal standard solution, and dilute with absolute ethanol to prepare a series of mixed standard solutions. The concentrations of the pre...

Embodiment 3

[0108] According to the method steps of measuring the content of xylene musk and sesamol in the sample of tobacco additives in Example 2, three kinds of solvents of dichloromethane, chloroform and carbon tetrachloride are respectively selected as the extraction agent to carry out sample pretreatment, and the measurement results are shown in image 3 . Depend on image 3 It can be seen that dichloromethane, chloroform and carbon tetrachloride can be used as extraction agents for sample pretreatment, but dichloromethane has the best extraction effect.

Abstract

The invention provides a method for measuring musk xylene and sesamol in a tobacco additive. The method comprises the steps of adding an isotope internal standard solution of a to-be-measured compound to the tobacco additive, carrying out dispersive liquid-liquid extraction and measuring the content of musk the xylene and the sesamol in the tobacco additive by using a gas chromatography-mass spectrometry. The method for measuring the musk xylene and the sesamol in the tobacco additive is simple and convenient to operate, green, environment-friendly and high in sensitivity; accurate and effective measurement of a trace of musk xylene and sesamol in the tobacco additive can be achieved; and the method can be applied to quality control of the tobacco additive.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical testing of tobacco additives, and relates to a method for measuring xylene musk and sesamol in tobacco additives, in particular to a method for measuring xylene musk and sesamol in tobacco additives by means of isotope dilution-dispersion The liquid-liquid extraction method is used for extraction, enrichment and purification, and the method is determined by gas chromatography-mass spectrometry. Background technique [0002] In the design and production process of cigarette products, it is often necessary to add various additives, such as flavors and feed liquids, preservatives, humectants and combustion enhancers, etc., to improve the physical and chemical properties of tobacco and cigarette products to meet the requirements of production and processing. demand and improve product quality. At the same time, the use of these additives also makes them an important factor affecting the...
