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.

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.

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.

A device for determining the distribution of glycation of erythrocytic membranes includes a container as a cell for electromagnetic-phoresis, a cathode ray and an anode ray which are connected to a direct current power supply, and a magnetic sheet which is placed outside the bottom of the container. The container has an upper surface containing a cathode hole, an anode hole, a filling hole midway between the cathode hole and the anode hole for a specimen, and an excretory hole for releasing air bubbles. After physiological saline is poured into the container, the cathode ray and the anode ray are respectively inserted into the holes to be soaked in the saline. Subsequently, a specimen of erythrocytes, which are bonded with the boric acid-magnetic beads, is infused into the container through the filling hole.

摘要:
An injector has a sample chamber for retaining a small amount of sample, wherein a position of the sample chamber is controlled by transmitting light through the sample chamber and detecting the transmitted light so as to recognize the position of the sample chamber, and it is possible to reduce detection error compared to the conventional injectors that indirectly control the position of the sample chamber by transmitting light through the light passage which is adjacent to the sample chamber. A method for injecting a sample comprising the steps of: providing an injector which has a sample chamber for retaining a sample with an open month; transmitting light through the sample chamber; detecting the transmitted light so as to recognize a position of the sample chamber; and controlling the position of the sample chamber by using the detection result to connect the open month of the sample chamber to an open month of a sample receiving member in order to inject the sample into the sample receiving member.
