Abstract
The oscillation frequency equation for an electrode-separated piezoele ctric sensor (ESPS) in a liquid phase was derived theoretically and ve rified experimentally. The dependences of the frequency shifts on cond uctivity, permittivity, density and viscosity of the liquid were inves tigated. The ESPS was applied to determine in situ the adsorption amou nt of hexadecetyltrimethylammonium bromide on a quartz surface. (C) 19 97 Elsevier Science S.A.
