A computer (14) implemented on-line method of monitoring (12, 26) and controlling (22) a chemical process is used for maximizing the yield of ethanol, sugars such as glucose and xylose and by-products such as silica or silicates from a biomass. The concentration of process reactants and products is sampled (10) and measured using spectrometric technology. The spectral data is stored and analyzed in the computer (14) using a modified chi-squared processing method to determine the unknown concentration of reactants and products in test samples (10) withdrawn from the process reactor (11) product stream. The need for the spectral data to conform to Beer's Law is avoided; the best spectral range is determined automatically; and the physical parameters (12) of the process are monitored (12, 26) and altered (20, 22, 24) based on this determination as required to optimize biochemical actions in the process reactor (11).
