Magnetic extraction

extraction probe

Analytical performance:

Extraction of magnetic minerals from resuspensed sediments using 10 sets of 3 extra-strong Neodymium magnets in combination with pure Iron extensions (fingers). The usable length of these 'fingers' is about 20 mm with a diameter of 8 mm. The iron fingers are protected by a teflon hose in order to enable the recovery of the collected magnetic particles from the extraction probe. Normally, a suspension is made from about 3-6 ccm of sediment dispersed in 50 ml of liquid, that is, water and/or alcohol. The extraction probe is submersed into the previously ultrasound-stirred slurry for a few minutes to hours.

Applications:

  • Extraction/concentration of the magnetic phase from unconsolidated marine or lacustrine sediments for further detailed studies.
