Abstract
This study deals with the simultaneous determination of L-ascorbic acid (L-AA) and glucose in mixture solution samples, by using terahertz (THz) spectroscopy and partial least squares regression technique. A calibration set consisting of 34 binary mixture solutions was applied for the construction of PLS model. The proposed procedure was successfully applied for the simultaneous determination of L-AA and glucose with acceptable result. The root mean square error of prediction (RMSEP) of 16 prediction samples was determined to be 2.55% and 1.92% for L-AA and glucose, respectively. SDRpred of 2.880 and 4.730 could be obtained for L-AA and glucose, respectively
