Abstract
A real-time system and method for measuring stickies by separating high molecular weight non-fibrous species from low molecular weight non-fibrous species and sensing the concentration of the high molecular weight species. Specifically, a fiber slurry containing stickies is filtered to remove fibers, fiber debris, and other large contaminant particles from the fiber slurry, after which the carbon content of the filtered sample is measured. Next, the filtrate is ultrafiltered to separate stickies having a high molecular weight from the filtrate, and subsequently, the carbon content of the ultrafiltered sample is measured. Finally, the carbon contents are used to determine the microstickies concentration in the fiber slurry.
