Embodiment Construction
[0025] In combination with the accompanying drawings of the present invention, the technical solutions of the embodiments of the invention will be further elaborated in detail.
[0026] The present invention demonstrates intelligently analyzing GC-MS data through the following examples to accurately realize compound identification and differential component screening.
[0027] S1. GC-MS signal acquisition
[0028] In order to obtain as many volatile and semi-volatile components as possible in tobacco plant samples, the samples were derivatized. The details are as follows: (1) Weigh 20 mg of the sample, extract the chemical components with methanol and chloroform, and derivatize with BSTFA at room temperature for 60 minutes. Take 1 μL for GC-MS analysis.
[0029] The GC-MS conditions were set as follows: chromatographic column DB-5MS 60 m×0.25 µm×0.25 mm. The temperature was programmed to rise from 70 °C to 310 °C at a rate of 3 °C min-1. The inlet temperature was 180 °C. ...
