Cigarette Small Box Trademark Paper Electronic Noses Fingerprint Of The Establishment And Application

This paper studies the use of electronic nose in Cigarette small box trademark paper volatileorganic compounds (VOCs) smell the application of evaluation, the purpose is to explore the objectiveand accurate to quickly evaluate the overall information of Cigarette trademark paper volatile organiccompounds (VOCs) method. Found a Cigarette small box trademark paper smell statistical qualitycontrol model.Applying principal component analysis (PCA),Soft Independent Modeling of Class Analogies(SIMCA), statistical quality control (SQC),Shelf-life (SL) chemometrics analysis method to the scentfingerprint(SF) applied research, Some Results As Follows:1. Through experiment design, inspection parameters optimization of electronic nose, The resultsshow that: When data acquisition time120s, headspace temperature60℃,sample volume1400ul,headspace time20min, the repeatability and distinguish is best. Meanwhile, building a Cigarette smallbox trademark paper of Qingdao Cigarette Factory smell fingerprint library.2. Through principal component analysis (PCA),Soft Independent Modeling of Class Analogies(SIMCA) analyzing,The results show that: The electronic nose can distinguish different cigarette brandsmall box trademark paper and the same cigarette brand of the different manufacturers. At the sametime,it can identify an unknown samples.3. Through the statistical quality control (SQC) analysis and GC/MS detected data validation, Theresults show that: based on electronic nose scent fingerprint(SF) data of different batche samples,building up the smell statistical quality control model, able to quickly evaluate the sample smellinformation, to judge the abnormal samples.4. Through Shelf-life (SL) analysis, The results show that: in storage process,the volatile organiccompounds (VOCs) of Cigarette trademark paper is in a declining process.For seven days, the smellhave significantly reduced and it is In the lower state.5. Draft the enterprise standard laboratory method of《E-nose technology application quicklyevaluation with Cigarette small box trademark paper smell》.
