摘要： A cutting apparatus for use in a sampler is disclosed. The cutting apparatus includes an extension tube having a round unit on a bottom side of the extension tube; a cutting ring located in a bottom portion of a protecting tube; a guide tube which is internally equipped within the cutting ring; a plurality of cutters equipped to an outside of the cutting ring for closing a bottom portion of the sampling tube when the cutting ring is pulled by uplifting an up-lifting rod of the sampler, wherein a plurality of the cutters are uplifted followed by the guide tube and bended according the round unit in order to be gathered and closed; and a connection means for fixing a plurality of the cutters on the cutting ring. A sampler having the cutting apparatus can gather a sample of un-cohesive soil such as a sandy soil without spilling.

摘要： The present invention relates to a surface treatment method for magnetic particles, a magnetic composite prepared thereby, and a magnetic composite for labeling target materials. More specifically, the invention relates to a surface treatment method for magnetic particles and a magnetic composite having excellent dispersibility prepared thereby, wherein the surface treatment method comprises the steps of: performing the acid-treatment of magnetic particles and mixing the acid-treated magnetic particles with a water-soluble solvent in order to form a hydroxyl group (—OH) on the surface of the magnetic particles; and mixing the magnetic particles, in which the hydroxyl group is formed, with a surface treatment agent containing an organic ligand, which can be bonded to the hydroxyl group, so that the organic ligand is treated on the surface of the magnetic particles.
