Determination of Organic Contaminants Concentration on the Silica Surface by Lateral Force Microscopy

Ivliev, N., Kolpakov, V., Krichevskiy, S., Kazanskiy, N.

Abstract.We present a method for determining the concentration of organic contaminants on the silica surface by using lateral force maps and surface topology images obtained with scanning probe microscopy. In this study, we optimized the scanning frequency to increase image contrast and facilitate interpreting data obtained. We also proved experimentally that the sensitivity of the method reaches 10−11 g/cm2.
