    Abstract: PURPOSE: Provided is a method of detecting vitamin E in the serum which extracts the vitamin E from the serum, and provides optimum analyzing conditions with selective and excellent sensitivity to the high performance liquid chromatography and ultraviolet ray absorber. CONSTITUTION: A method of detecting the vitamin E in the serum comprises the steps of: treating the serum by a buffer solution containing 0.075-0.2M of salt with pH4.0-5.5; extracting the vitamin E from the treated serum by diethyl ether; and analyzing the concentration of the extracted vitamin E by a high performance liquid chromatography with a ultraviolet ray absorber. The serum is derived from livestock, the buffer solution from phosphoric acid or acetic acid, and the salt from NaCl.

    Abstract: PURPOSE: A polymer culture dish having an improved hydrophilic property and surface adhesiveness is provided which a part of carbon of the activated surface is reacted with a reactive gas after activating the surface by irradiating less than 2,000 eV of ion-beam. CONSTITUTION: A surface modifying apparatus comprises a gas inlet part(20) introducing a reactive gas into a vacuum chamber(10), an ion source(30) producing ion beam, a substrate holder(40) and a vacuum pump(50). The polymer culture dish is built in the substrate holder(40) and the reactive gas is introduced into the vacuum chamber(10) through the gas inlet part(20). Ion-beam having less than 2,000 eV is irradiated to activate the surface of the polymer culture dish from the ion source(30). The surface of the polymer culture is reacted with the reactive gas such as oxygen, nitrogen, carbon dioxide, carbon monoxide, ozone and their mixed gas to produce a hydrophilic group on the surface.
