1) preparation of cigarette sample
Collecting B trade mark cigarette, closely different batches cigarette sample, each batch choose 3 cigarette (nominal cigarettes in parallel in two years
Do not select) be fitted into the ml headspace bottle of 20ml seal it is to be measured.
2) cigarette sample is analyzed using HS-GC-IMS
Analysis condition is the same as example 1.
3) sample analysis and spectrogram are evaluated
115 different batches cigarette samples for analyzing different factory's productions in B trade mark cigarette 2015 to 2017 years, in three-dimensional spectrum
Upper selection 20 signature analysis regions of the cigarette, carry out principal component analysis (PCA) to it using spss software, and PCA utilizes dimensionality reduction
Thought, exclude information overlapped in numerous information under the premise of losing little information, multiple indexs be converted into several
A incoherent overall target, that is, principal component, it is irrelevant between each principal component so that principal component than original variable have it is certain more
Superior performance reaches simplied system structure from face, catches the purpose of question essence.This example sample size 115, variable 20,
Kaiser-Meyer-Olkin and Bartlett sphericity test is carried out after being standardized dimension processing to sample matrix:
Table 1
As shown in Table 1, KMO > 0.6, and the associated probability that Bartlett sphericity test provides is 0.000, is less than conspicuousness
Level 0.05 illustrates that sample is suitable for carrying out principal component analysis.Analysis obtains principal component 4 that characteristic root is greater than 1, adds up variance
Contribution rate 84% is three-dimensional shot chart such as Fig. 5 to preceding 3 principal components and shows have the cigarette of 7 batches to have exceeded 95% confidence
Section, wherein confidence interval of 5 batches close to 95%, 2 batch samples far from 95% confidence interval, at this time in combination with carrying
It is which variable causes the point far from confidence interval that lotus figure, which is checked, and look for reason from raw data table: whether data handling procedure has
It misses, or analysis evaluated error or sample itself quality fluctuation reason cause.
In conclusion a kind of method for identifying Volatile Components in Cigarette stability provided by the present invention, by acquiring not
