METHOD FOR ANALYSIS OF CRUDE PROTEIN IN CEREAL EMPLOYING FTNIRDRSA

本方法是用FTNIRDRSA测定谷物中的粗蛋白含量,内容包括五个部分:测定原理和范围;方法的提要;所用设备;测定步骤(包括样品制备,样品近红外光谱的扫描,仪器的定标,定标方程的评价,方程斜率的检查,偏差,准确度和精确度的检查)以及结果的表述。

This paper is concerned with the method for FTNIRDRSA.It is applicable to deter- mination of crude protein content in cereal employing FTNIRDRSA.It contains five parts:prin- ciples and scopy,abstract of method,apparatus,procedure(preparation of samples,scanning NIRS of samples,calibration of the instrument,assessment of the calibration equation,check for skew,chek for bais,check for accuracy,check for precision and determination of samples)and presentation of results.
