Hello, I am relatively new to NIR spectroscopy and I am working on a project to determine the composition of five different waste solvent tanks all with varying compositions of seven solvents. Initially, I am making seperate models for each waste tank and the ultimate goal is to build a model capable of analysing waste from any waste tank. I have been using pls2 mainly for modelling and having been using MSC because of scattering caused by dissolved solids in the waste. I get good correlation, but the predictive ability of the models are bad. I can't figure out why this is. Does anyone know of any literature/published papers dealing with a similar type of problem that I could look up? I will also be establishing an on-line NIR method for analysing streams leaving and entering distillation columns for the solvent recovery process, so any information on this would also be greatly appreciated. Thanking you with regards, Michael Hodge |
