title: Characterization of Nonmicrobiological Paper Mill Deposits by Simultaneous TG-IR-MS.
abstract: The problem of deposits and their identification is one of the most persistent ones facing paper mills. Materials other than fibers accumulate in closed water circulation systems and may appear as impurities in pulp and paper or can contaminate wires and felts or build up deposits at various points in the mills. Traditionally, chromatographic and spectroscopic methods have been employed in the analysis of deposits and other pulp and paper process impurities. Simultaneous thermogravimetry-infrared-mass spectrometric (TG-IR-MS) analysis is a relatively new technique which, when applied to the analysis of mill deposits, provides a rapid means of identifying the source of these contaminants.
