Problems solved by technology

The test process uses n-hexadecane, pristane and toluene as standard oils, but the actual oils involved in cigarette production are not these types, but specific types, which makes the comparability poor and leads to accurate detection low degree

Embodiment Construction

[0035] Five types of oils directly related to cigarette production were collected from the workshop: GD cigarette packaging machine filter 10# oil, GD cigarette packaging machine host EP150 oil, Protos cigarette rolling machine cutter head D68 oil, Protos cigarette rolling machine The host machine H100 oil and grease; these oils are mixed compounds of various hydrocarbons, it is not easy to find a suitable solvent to dissolve them completely or as completely as possible, and at the same time to obtain a better chromatogram ;Analyze on gas chromatography / mass spectrometry, determine a good chromatographic condition, and obtain a relatively ideal chromatographic peak separation effect and chromatogram; for actual oily cigarette treatment, generally the sample amount of oily smoke is small, and the volatile components may have volatilized, Whether to adopt a concentrated method to improve its detection sensitivity and finally determine an optimal experimental plan.

Abstract

The invention relates to the technical field of chemical detection of cigarettes, and especially provides an identification method for oil stained cigarettes. The GC / MS identification method for oil stained cigarettes comprises the following steps: 1) collecting a plurality of types of oil directly related to production of cigarettes and respectively dissolving and extracting the types of oil with ethyl acetate; 2) adjusting GC / MS parameters, carrying out gas phase / mass spectrometry detection on the extracted solutions of oil, establishing different chromatograms to form a chromatogram database, and determining fingerprints; 3) taking cigarette papers having oil stains, immersing the cigarette papers with ethyl acetate, carrying out extracting, concentrating the extract with a distillation apparatus, and carrying out gas phase / mass spectrometry on the concentrate to obtain a chromatographic fingerprint; 4) comparing fingerprints of the chromatographic fingerprint of oil stained cigarettes with fingerprints in the established chromatogram database to identify which oil stain is on the oil stained cigarettes. The invention enables fast and effective identification of oil stains generated in the production of cigarettes, provides a basis for identifying a problematic process in the production of cigarettes, and allows problematic cigarettes to be traceable.

Description

technical field [0001] The invention relates to the technical field of cigarette chemical detection, and in particular provides a method for identifying oily cigarettes. Background technique [0002] "Grease-stained smoke" is often found in the inspection of finished cigarettes, but inspectors cannot identify whether it is real oil-stained smoke, nor can they determine which production process produced it. At present, there is no relevant scientific method for the determination of oily smoke. It is mainly based on human visual inspection, but there will be certain errors. According to literature search, there is no scientific identification method in China so far. If a scientific method can be found to identify the types of oil stains, it will have certain practical significance for the traceability and quality assurance of cigarette products. [0003] "GB / T 16488-1996 Determination of Water Quality Petroleum and Animal and Vegetable Oils by Infrared Photometry" is applicab...
