Method for determining volatile components of tobacco blasting bead by solid phase microextraction-gas chromatography-mass spectrometry

Abstract

chromatography-mass spectrometry, the method comprises the following steps: 1) placing the blasting bead into a solid phase micro-extraction bottle, crushing, covering the solid phase micro-extractionbottle with a solid phase micro-extraction bottle cap, then heating to volatilize and balance components in the blasting bead; aging a solid phase micro-extraction head; 2) inserting the solid phasemicro-extraction head into the solid phase micro-extraction bottle, and adsorbing at 40-120 DEG C for 60-240 min; 3) inserting the adsorbed solid phase micro-extraction head into a sample inlet of a GC-MS instrument, and thermally desorbing at 230-280 DEG C for 1-2 min; and 4) running the GC-MS instrument and collecting data. The method can conveniently, quickly and accurately analyze the volatilecomponents in the blasting bead and avoids the interference and pollution caused by a solvent in the blasting bead. The peak type has no tailing phenomenon, and the components are separated. The components basically cover the common components of the blasting bead, and the method has a good separation and detection effect, and provides an analytical basis for the research and development of a newblasting bead, quality control of blasting bead production, component analysis of blasting bead products, and the like.

Description

technical field

[0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for determining the volatile components of popping beads for cigarettes by solid-phase microextraction-gas chromatography. Background technique

[0002] In recent years, the appearance of "popping beads" filter sticks has made the methods of tobacco flavoring more diversified, and the use of some extremely volatile and unstable flavors and fragrances and functional additives has also become possible. The functions of "Bangzhu" in supplementing, improving and coordinating the quality of cigarette smoking and improving, changing, and the style of cigarette products are becoming more and more prominent. Consumers welcome.

[0003] The so-called Breakable Capsules, also known as incense pills, brittle capsules, and beads, have a diameter of 26-35 μm and a weight of about 0.020 g. They refer to beads that can be squeezed. It is used in sticks and to a lesser ext...
