Abstract: | The model application performance of the newly developed grating type domestic NIR spectrometer was evaluated.72 wheat samples with known chemical values of crude protein were selected for modeling and analysis.Two S450 domestic NIRS and one imported Fourier transform NIR were selected as test instruments.The test and evaluation items included:performance comparison of instrument models,stability test of instrument models,and model transfer test between different instruments.The experimental data show that the model index of the new domestic near infrared spectrum analyzer is up to the level of imported instruments,and the model transmission performance is good,which can meet the practical application demand of NIR. |
