    摘要: A material is provided for capturing a chemical substance comprising fibers which carry metal alkoxide particles on the surfaces thereof. The metal alkoxide particles are made from an oligosilica, an oligozirconia, an oligotitiania, or the like. The fibers may include inorganic fibers, regenerated fibers and/or synthetic fibers. The material for capturing a chemical substance is produced by a method comprising steps of subjecting the fibers to a surface treatment for facilitating adhesion of the metal alkoxide particles to the surfaces of the fibers, forming the metal alkoxide particles on the surfaces of the fibers, and fixing the metal alkoxide particles to the surfaces of the fibers. A chemical substance-capturing tube, capable of capturing a trace of a chemical substance in a liquid or a gas, can be produced by placing the fibers, i.e., the material for capturing a chemical substance, in a hollow tube.

    摘要: The liquid pump has a pressure vessel with end-openings for hermetically holding liquid therein. The liquid flows from one of the end-openings to the other end-opening by utilizing a difference in a coefficient of thermal expansion of the pressure vessel and the liquid caused by heating or cooling the pressure vessel and the liquid together. The pressure vessel is a tube having an inner diameter of about 0.5 mm or less and a length of about 10 m or more.

    摘要: In an open capillary column, a stationary phase is formed on the inner wall of a capillary tube. This stationary phase comprises a number of pores on the surface of the capillary tube, and each of pore has an expanded hollow in the stationary phase. A manufacturing method of an open capillary column comprises the steps of giving alkaline treatment to an inner wall of an open capillary tube, applying one of oligo silica, oligo zirconia and oligo titania on the inner wall, filling the open capillary tube with alkaline solution to form one of a silica layer, a zirconia layer and titania layer, discharging the alkaline solution and heat-treating the capillary tube to form a base of a stationary phase. The open capillary column of the present invention comprises a stationary phase having a very large surface area. It is useful for a separation analysis field such as liquid chromatography and electrochromatography.

    摘要: A change in physical properties of a fluid within an open tube which is caused by heating an arbitrary portion in the open tube by heating means is detected by using a detector disposed with a predetermined spacing from the arbitrary portion, thereby measuring the flow in the open tube. The present invention provides a method for measuring flow within an open tube, in which a mechanical error and contamination of a passage do not occur, as a method for measuring flow within an open tube having a very small diameter provided for the separation analysis field and chemosynthesis field.
