  • Working principle and application of magnetic separation

    Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose. For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis. This separation process not only can be achieved via the

  • Magnetic Separation in the Mining Industry Mainland

    2015-04-29· Why Magnetic Separation Matters for the Mining Industry. One of the greatest challenges facing the mining industry is the separation of unwanted material generated by the extraction process from the valuable material. Mining, whether done through open seam or underground means, creates a huge amount of waste product in the form of worthless or low value minerals and unusable man-made

    The magnetic deposition protocol allows quantitative detection of E. coli down to the concentrations of lo5 cfu m1-l. A procedure for the preparation of magnetized bacterial cells has been described, based on the precipitation of ferro ions as hydrogen phosphates or sulphides on their surface (Ellwood et al. 1992). Such bacteria, due to the specific properties of the altered cell wall, could

  • Rare Cell Separation and Analysis by Magnetic Sorting

    The current effort in magnetic separation focuses on miniaturization, in flowing or static media, by either selective immobilization and deposition or magnetic deflection. (9-12) However, the magnetically deposited cells may be difficult to recover compared to the magnetic deflection-based systems and, therefore, require direct interrogation in situ by optical means (13) or electrochemically.
