A magnetic levitation system is described, including a first and second magnets having surfaces of their like-poles facing each other; and a container disposed between the first and second magnets' like poles and containing a solution including a paramagnetic complex in a non-aqueous solvent, where the paramagnetic complex includes a paramagnetic metal and at least one ligand that coordinates to the paramagnetic metal via electron donation. Methods of separating a mixture of solid compounds, and/or identifying, confirming, and/or predicting the composition of the mixture, are also described.

Magnetic levitation system

A device is disclosed, including: a plate including a sample deposition tube adapted to receive a sample comprising one or more analytes, the sample deposition tube defining a vertical axis substantially perpendicular to a main surface of the plate; and a mirror positioned to project, substantially parallel to the main surface of the plate, an image of the sample deposition tube along its vertical axis, so as to allow determination of the vertical location of the one or more analytes inside the sample deposition tube. Methods for determining the density of one or more analytes using various embodiments of the device are also described.

Sample analysis with mirrors

A magnetic levitation system is described, including a first cylinder-shaped magnet; a second cylinder-shaped magnet coaxially aligned with the first cylinder-shaped magnet; and a first cavity coaxially aligned with the first cylinder-shaped magnet; wherein the surfaces of the like-poles of the first and second cylinder-shaped magnets are parallel to each other and face each other to result in a linear magnetic field between the first and the second magnets. Methods of using a magnetic levitation system for analyzing a diamagnetic or paramagnetic sample are also described.
