Abstract

Magnetic levitation (MagLev) is a technique used to measure density of an object in a paramagnetic media that is suspended between two magnets with like poles facing each other. In this study, MagLev was used to measure the density of drug tablets from different sources. A tablet is placed in a container filled with a paramagnetic ionic liquid and the container is placed between two NdFeB magnets oriented with like poles facing. The density of the tablet can be calculated from its levitation height, measured relative to internal density standards of known density, using a ruler with mm-scale markings. Tablets from pharmaceutical suppliers showed well-defined densities. Distinguishing differences in density between tablets by MagLev provides an operationally easy way to screen for tablets that are counterfeit. This simple density-based method for screening maybe particularly useful in resource-limited settings, or in regions with poor regulatory and quality control.
