Determination of Chemical Components of Handed Tobacco Leaves by NIRS

摘要: 為在收購(gòu)現(xiàn)場(chǎng)及時(shí)向質(zhì)檢人員提供煙葉化學(xué)成分?jǐn)?shù)據(jù),，更加全面準(zhǔn)確地判斷煙葉質(zhì)量，減少煙葉樣品前處理工序,，直接在把煙葉表選取10個(gè)特殊點(diǎn)采集近紅外光譜，然后合并為一個(gè)平均光譜,，與流動(dòng)分析儀檢測(cè)化學(xué)成分結(jié)果進(jìn)行關(guān)聯(lián),，建立數(shù)學(xué)模型，各成分模型相關(guān)性均在0.9以上,。初步應(yīng)用證明該套近紅外模型基本滿足設(shè)計(jì)需要,。

Abstract: In order to provide on site chemical analysis data of tobacco leaves to quality agent at purchase, NIRS method was used to determine the chemical component of tobacco leaves. The ten points of handed tobacco leaf surface was combined into one mean spectrum, which was correlated with the determination results of chemical components by flow analyzer, and the mathematical models were established with average correlation coefficients over 0.9. The designed NIRS model is reliable and practical for chemical components determination of handed tobacco leaves.
