• Near-infrared was used to develop a method for on.line quality control in the percolation and concentration process of Gegen
• Calibration models are generated by partial least.squares.(PLS) regression as linear regression and artificial neural networks.(ANN) as non.linear regression
• The root mean square error of prediction for the PLS and ANN model was 0.0396 and 0.0365 and correlation coefficients.(r²) was 97.79% and 98.47%, respectively.
