USE OF A SOLID FRACTION SENSOR TO EVALUATE A SOLID FRACTION OF A TARGET PHARMACEUTICAL SAMPLE AND SOLID FRACTION SENSOR

摘要

For the use of a solid fraction sensor (17) to evaluate a solid fraction of a target pharmaceutical sample (4, 10) the solid fraction sensor (17) has a first conductor element (5), a second conductor element (7), an operation space (15) and an energy source (13) arranged to generate an electric field in the operation space (15) by means of the first conductor element (5) and the second conductor element (7), comprising positioning the target pharmaceutical sample (4, 10) in the operation space (15) of the solid fraction sensor (17), determining a capacitance between the first and second conductor element (5, 7) with the target pharmaceutical sample (4, 10) located in the operation space (15), and converting the determined capacitance together with information about a composition of a reference pharmaceutical sample having the essentially same dielectric properties as the target pharmaceutical sample (4, 10) and about a thickness of the reference pharmaceutical sample (4, 10) into a solid fraction of the target pharmaceutical sample (4, 10).
