When a molecular ion of mass m 1 carries a single positive charge, it may decompose in front of the magnetic sector to form a fragment ion of mass m 2 and a neutral fragment. If there is no kinetic energy of separation of the fragments, the ion m 2, and also the neutral fragment, will continue along the direction of motion of m 1 with unchanged ...
Ion separation. Ion separation is another application of magnetic separation. The separation is driven by the magnetic field that induces a separating force. The force differentiate then between heavy and lighter ions causing the separation. This phenomenon has been demonstrated on test bench and pilot scale. References
Dec 02, 2003· The magnetic separation was investigated for Co2+ (9500 × 10-6 cm3 mol-1) and Fe3+ (14600 × 10-6 cm3 mol-1) ions and for Cr3+ (6200 × 10-6 cm3 mol-1) and Al3+ (−2 × 10-6 cm3 mol-1) ions. The metal ion solutions were spotted on a silica gel support, and exposed to a magnetic field of 410 kOe2 cm-1 intensity × gradient. The Co2+ ions move farther toward the maximum field than the Fe3+ ions.
The possibility to enrich paramagnetic dysprosium(III) ions in a magnetic field gradient is proved by means of interferometry, which may open the route for a magnetic separation of rare earth ions ...
Disclosed is a new method for magnetic separation from a carrier fluid of biological cells or other organic or inorganic particles having a negative surface charge. A paramagnetic salt is mixed with an aqueous solution of a chelating agent, for example EDTA. The cells or particles to be separated are mixed with this paramagnetic carrier solution, and the resulting mixture is exposed to a high ...
Magnetic field creates an opposite drift velocity on the hydrated paramagnetic ions against the flow of the sample zone, retards the moving velocity of the metal ions and provides extra contacting ...
Sep 19, 2013· A significant decrease in the concentration of copper(II) ions in the supernatant solution was observed. An extremely sensitive method based on surface‐enhanced Raman spectroscopy was employed to detect free copper(II) ions that remained after the magnetic separation, and thus to evaluate the separation efficiency.
Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...
This limitation is overcome in Double Focusing Mass Spectrometer, where the ions are lead through a radial electrostatic field prior to magnetic separation. Therefore, ions with same kinetic energy are only fed to the magnetic sector and thus velocity focusing is achieved.
Nov 26, 2004· Isolation and separation of specific molecules is used in almost all areas of biosciences and biotechnology. Diverse procedures can be used to achieve this goal. Recently, increased attention has been paid to the development and application of magnetic separation techniques, which employ small magnetic particles.
An apparatus for the separation of oppositely charged ions comprises a body including an inlet fluidly coupled to a first outlet and a second outlet. A flow director including a discharge is disposed in the body between the inlet and the first and second outlets. The flow director is configured to fluidly couple the inlet and the first and second outlets.
Jan 15, 2018· Magnetic separation is a simple and yet effective method for many separation processes from biotechnology to ore dressing where removal of certain particulates from solutions are required. ... (Li 2 TiO 3), iron ions were doped into Li 2 TiO 3 to prepare magnetic lithium ion-sieves adsorbents (Fe-doped Li 2 TiO 3). The resulting material ...
ICR is an ion trap that uses a magnetic field in order to trap ions into an orbit inside of it. In this analyzer there is no separation that occurs rather all the ions of a particular range are trapped inside, and an applied external electric field helps to generate a signal.
The Cr 3+ ions move farther toward the field center than the Al 3+ ions. This occurs because the Cr 3+ ions are attracted more strongly by the magnetic force than the Al 3+ ions. It is demonstrated that the separation makes effective use of the adsorption activities as well as the magnetic susceptibilities.
This is another strong support for Commun., vol. 1, no. 8, pp. 319–323, 1999. the possibility of a magnetic separation of paramagnetic ions  M. Uhlemann et al., "Structured electrodeposition in magnetic gradient although the underlying physics is not fully understood.
