摘要
为探索快速准确测定滤棒中三醋酸甘油酯含量的方法,利用近红外漫反射光谱技术和偏最小二乘法,建立了滤棒中三醋酸甘油酯含量测定的数学模型,并对所建立的数学模型进行了优化和验证。结果表明,该方法具有简单快速、无损、准确的特点,无需样品预处理,特别适合于大量重复性样品的分析测定。
In order to determine triacetin in cellulose acetate filter rod quickly and accurately, a mathematical model was developed with near infrared diffuse reflectance spectroscopy and partial least square, and the model was optimized and verified. The results showed that the method is fast, accurate and especially suitable to where there are mass filter rod samples to be analyzed.
