ABSTRACT:
A method for measuring extremely low concentrations of non-aqueous constituents or chemicals in a water/matrix, including differentiating between pulp fines and extremely low concentrations of individual chemicals in a water/cellulose matrix such as occur in papermaking. The water/matrix is exposed to the near-infrared spectrum from 1000 to 2500 nm to produce a recorded voltage that is directly proportional to the absorption by the non-aqueous constituent. The amount non-aqueous constituent is determined from stored voltage values of incremental additions of the non-aqueous constituent.
