ABSTRACT:
A method for monitoring the deposition of one or more organic materials dispersed in an aqueous medium in a papermaking process comprising: measuring the rate of deposition of the organic materials from the aqueous medium on-to a quartz crystal microbalance having a top side contacting with the aqueous medium coated with a layer containing a non-swelling epoxy resin or a silicone containing polymer, and a second, bottom side isolated from the aqueous medium is disclosed. Additionally, a method for measuring the effectiveness of an inhibitor that decreases the deposition of the organic materials in a papermaking process is also disclosed.
