Abstract:
The present invention relates to a method of extracting a sample solution for analysis of an oil contaminant component from a marine sediment sample. The extraction method of extracting the sample solution for analysis of oil contaminants comprises a sample treatment step (S1) in which a top cap (12) with a solvent inlet (12a) and a bottom cap (13) with a sample extraction hole (12a) are assembled on the top and bottom of a cylindrical extractor body (11), respectively, and frozen and dried marine sediment (15) for sample extraction is inputted into an extraction kit (10) made of stainless steel material with a filter (14) on the inner bottom surface of the extractor body (10); and a sample extraction step (S2) of heating the extraction kit (10) by mounting the extraction kit (10) on an accelerated solvent extraction device and pressurizing and injecting a solvent into the extraction kit (10).
Abstract:
PURPOSE: A device for collecting seawater samples is provided to perform the piston operation of a seawater injector safely and securely by a piston clamper, a clamper load, a coil spring, and a switching lever based on the guide post of a sampler body. CONSTITUTION: A device(10) for collecting seawater samples comprises a seawater tank(2), a sampler(3), and a control tool(4). The sampler collects the seawater from the seawater tank and includes a sampling motor and a plurality of seawater injectors. The sampling motor is installed inside a motor casing(31) and connected to a control tool. The seawater injectors are installed along a sampler body(33) installed outside the motor casing.
