| 摘要 |
The invention relates to a method for measuring a magnetic property of magnetic nanoparticles, comprising the following steps: conducting a liquid (29), which contains the nanoparticles (31), through an alternating magnetic field (B), measuring a magnetization parameter, which describes a dependence of a magnetization of the nanoparticles (31) on the alternating field (B), and conducting the liquid (29) through a wound capillary (30) through the alternating magnetic field (B). According to the invention, before the liquid (29) is conducted through the wound capillary, the magnetic nanoparticles (31) are fractionated in the liquid (29) such that a fractionated liquid flow arises, wherein the measurement of the magnetization parameter is a time-resolved measurement of the magnetization parameter performed on the fractionated liquid flow. |
