A method for monitoring with enhanced sensitivity of the deposition of one or more organic materials dispersed in an aqueous medium in a papermaking process which includes measuring the rate of deposition of the organic materials from the aqueous medium onto a quartz crystal microbalance having a top side contacting with the aqueous medium coated with a layer containing a material with surface energy in the range from about 34 to about 49 dynes/cm2, 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.
