The purpose of this project is to determine the concentration of hydrogen peroxide (H2O2) over the unknown test sample. Near-infrared spectrometry (NIRS) is the spectroscopic technique used to assess the concentration of a chemical species based on the molar absorptivity in the Near-infrared (NIR) band. A multivariate statistical analysis tool will be applied to distinguish spectra for H2O and H2O2 through pre-processing stage. Then, multivariate regression method is applied to the
