The present invention aims to provide a method for preparing a peptide-containing sample that enables identifying a greater number of trace proteins in proteome analysis of biological samples such as dried blood spots (DBS), and that allows for the automated processing of a large number of samples. By washing a fiber aggregate having a biological sample adsorbed thereon with an aqueous solvent, hydrophilic proteins contained in the biological sample are removed from the fiber aggregate. Residual proteins bound to the fiber aggregate are digested with a protease, and the fiber aggregate is removed from the digestion reaction mixture to obtain a peptide mixture. By allowing magnetic particles such as iron powder to be adhered to the fiber aggregate and magnetically adsorbing the fiber aggregate, operations such as recovery, washing, and transfer of the fiber aggregate having the biological sample adsorbed thereon are carried out. The present invention also aims to provide a technique for easily and reliably separating non-magnetic solid-phase carriers dispersed and suspended in a liquid from the liquid. By agitating a liquid containing magnetic particles and a non-magnetic solid-phase carrier, the magnetic particles are allowed to be adhered to the non-magnetic solid-phase carrier. The non-magnetic solid-phase carrier having the magnetic particles adhered thereto is then magnetically adsorbed and separated from the liquid. When a non-magnetic solid-phase carrier having a porous structure is used, magnetic particles can enter the voids within the porous structure through agitation, thereby allowing the non-magnetic solid-phase carrier to be more reliably magnetically adsorbed. When a thickening agent is added to the liquid, the sedimentation rates of the non-magnetic solid-phase carrier and the magnetic particles become equally small, allowing the two to mix well in the liquid and the magnetic particles to be uniformly incorporated into the non-magnetic solid phase carriers, thereby ensuring more reliable adsorption to the magnet.

A method is described for controlling an oil spill by seeding micron-sized magnetizable particles in the oil. Once seeded, particles can form a unique and preferential bond with the oil resulting in creation of a colloidal mixture. This bond forms as a result of a combination of forces including the intermolecular Van der Waal forces.
