Abstract
In this research, an explicit method of linear correction for temperature compensation was conducted for L-AA determination using Fourier transform infrared-attenuated total reflectance terahertz (FTIR-ATR-THz) spectroscopy. The explicit method was done by direct inclusion of temperature as y-variable in the PLS2 regression. The result showed that using explicit method the quality of the developed calibration model for L-AA determination is a little bit superior with RMSECV=1.387% (w/w) and SDRv= 4.311.The performance of the PLS2 calibration model for L-AA determination with temperature compensation was quite good and able to predict the L-AA in three different temperatures with relatively high R2pred values. All prediction also resulted in low bias and SEP values.
