亚麻油是重要的天然保健油。亚麻油中各种组分的定量分析,以往多采用气相色谱法,存在着方法繁琐、耗时较长的缺点,不适合生产时产品在线分析的需要。本文采用近红外光谱法(NIR)对亚麻油各种组分模型化后再进行定量分析,取得了满意的结果,基本达到了快速、无损、在线分析亚麻油的目的。
Linseed oil is an important natural health-care oil. Quantitative analysis of various components in linseed oil, the gas chromatography in the past, the use of more complicated, time-consuming shortcomings, is not suitable for production of online product analysis needs. In this paper, various components of linseed oil were modeled by near infrared spectroscopy (NIR) and then quantitatively analyzed. Satisfactory results were achieved, and the purpose of fast, nondestructive and on-line analysis of linseed oil was achieved.
