This document specifies a method for the determination of the silanol group content on the surface of fumed silica by reaction gas chromatographic method.
Abstract
Overview
specifies a laboratory procedure for the using a . Adopted by CEN from ISO, this standard provides a validated, reproducible route to quantify surface silanol groups - a key surface-chemistry parameter that affects dispersion, reactivity and performance of fumed silica in downstream applications.
