Abstract: A water vapor plasma generating apparatus which is able to generate water vapor plasma stably is provided. By applying the water vapor plasma generated by the apparatus to an object to be treated, a sterilization and disinfection treatment can be performed. In addition, by applying the water vapor plasma generated by the apparatus to a substance containing an oily ingredient, an antioxidative treatment can be performed.

Abstract: Disclosed is a method for separating a plurality of different chemicals in a sample. The method uses a hexyl-bonded stationary phase composition in reversed-phase liquid chromatography. The composition includes a polymer-based chromatographic support composed of chemically stable and porous particles having a surface. The surface of said particles having hexyl-phenyl bonded thereto. A chromatography column is packed with this composition and a sample including a plurality of different chemicals is injected. Liquid is applied to force the sample through the column, whereby said different chemicals come out of the column at different times.

Abstract: An alkyl-phenyl bonded a stationary phase for use in reversed-phase liquid chromatography, having five to ten carbon atoms in the alkyl group, is disclosed. The alkyl-phenyl bonded phase has its unique selectivity, and it is chemically stable in both acidic and basic environments as well as having high retention capacity, hence high resolution. A method for preparing the alkyl-phenyl bonded phase and a column inside of which the alkyl-phenyl bonded phase is packed with are also disclosed. Additionally, a method for performing liquid chromatography and a mixed stationary phase which has more than one alkyl-phenyl phases are disclosed.
