Abstract
A device for measuring an ionic concentration of an ionic compound in a porous medium solution contained in a porous medium. The device includes a sensing portion, a light source, and a light sensor. The sensing portion is miniaturized and includes a permeable material body defining a measuring cavity therein and is insertable in the porous medium to allow the porous medium solution to diffuse through the permeable material body. The light source illuminates the porous medium solution contained inside the measuring cavity. The light sensor detects a resulting light emanating from the porous medium solution, the resulting light having at least one spectral characteristic indicative of the ionic concentration of the ionic compound in the porous medium solution. There is also provided a method for measuring in situ an ionic concentration of an ionic compound in a porous medium solution contained in a porous medium.
