将目标变换因子分析中的自由浮动思想引入多元校正中,提出了一种新的多组分同时校正法——校正变换矩阵法。将该法应用于紫外分光光度法同时测定五种芳香族化合物,结果令人满意。与目标因子分析法和卡尔曼滤波法比较,本法具有更好的校正准确度。
The idea of free floating in the target transform factor analysis is introduced into multivariate calibration. A new multicomponent simultaneous correction method, a modified transformation matrix method, is proposed. The method was applied to the simultaneous determination of five aromatic compounds by UV spectrophotometry with satisfactory results. Compared with the method of target factor analysis and Kalman filtering, this method has better correction accuracy.
