Volume changes source

Transient solutions for the Nemst-Einstein equation have been derived assuming a constant source concentration [69]. An approximate solution may be obtained when the decline in source concentration is small over the time period of the study by assuming (a) a constant iontophoretic permeability coefficient Fionp (b) the donor iontophoretic compartment is a well-stirred solution (c) sink conditions exist and (d) the solute concentration in the donor solution Q of volume changes at a rate equal to the total flux JjA out of the compartment into the outer layer of the epidermis ... [Pg.308]

Methods based on measuring the undissolved gas content of the liquid direct measurement of the volume change effect of undissolved gas on the electrical impedance of the source, transparency of the liquid to light (UV-visible), diagnostic ultrasound, X-rays and effect on electrical or acoustic permittivity or conductivity. [Pg.8]
