Definitions
- the collector used for collecting the diluted liquid sample is silica gel fine particles, silica gel fine particles with a chemically modified surface ⁇ volima-fine particles, and silica gel fine particles entangled with glass fiber ⁇ tetrafluoroethylene fiber. It is known that an assembly of the above is held between frits and this is incorporated into a hollow polyethylene tube or a resin type of a syringe type, and is widely used for solid-phase extraction. The one in which the aggregate of the above materials is incorporated in such a resin mold has a drawback that the flow resistance is large. Another drawback is that a large amount of solvent is used to move the components in the sample.
- such a method for producing a chemical substance collector includes a step of performing a surface treatment to fix and masticate the metal alkoxide fine particles on the fiber surface, and a step of forming the metal alkoxide fine particles on the fiber surface. Fixing the metal alkoxide microparticles on the fiber surface.
- such a fibrous chemical substance collecting body is held in a hollow tube to form a chemical substance collecting tube for collecting a trace amount of a chemical substance in a liquid or a gas.
- FIG. 2 is a magnified micrograph of one glass fiber supporting silica fine particles produced by using the 3% oligosilicon force of Example 1.
- FIG. 9 is a chromatogram obtained by liquid chromatography showing the result of the collection of a chemical substance in a gas using the chemical collector of Example 5.
- the application of the oligosili force is performed by immersing the quartz glass fiber in a 30% origosiri force solution, and then removing the excess origosiri force solution from the quartz glass fiber surface by a centrifuge. During this process, the origosiri force remains on the quartz glass fiber surface.
- glass fibers carrying silica fine particles on the surface can be formed.
- the following manufacturing process 5 can be added to further enhance the ability to hold the target chemical substance.
- each solution passing through the collection tube is completely separated from the collection tube by centrifugation or vacuum suction. Recovery of the solution in the centrifuge field is performed by inserting a collection tube into the centrifuge tube.
- FIG. 5 showing the analysis results of the solution that has passed through the collection tube in each of the steps B to D will be described.
- B, C, and D indicate the injection points of the respective solutions of Steps B, C, and D
- B (sp), C (sp), and D (sp) indicate the respective solvent peaks
- D (op ) Indicates the target peak. From Fig. 5, the following results are obtained.
- step B there is a solvent peak B (sp) after injection of the sample solution containing 0.01% caffeine (B in FIG. 5), and then injection in step C (C in FIG. 5). Until then, a flat baseline continues.

- benzene vapor of 10 ppm was prepared in a tetrabag having an internal volume of 1 £.
- glass fibers carrying silica particles subjected to ODS treatment were collected and held as a bundle in a syringe. This bundle weighs 0.
- a standard gas was passed through this bundle to collect benzene vapor. That is, a syringe holding the above bundle (hereinafter, “small syringe”) is directly connected to one stopper of the tetra bag, another large syringe is connected to the back of the small syringe, and suction is performed with a large syringe.
- a standard gas (10 ppm benzene vapor) was passed through a bundle of glass fibers (small syringe). This gas passage operation was achieved quickly because glass fiber has little flow resistance to gas.
- the fine silica particles are chemically modified with octadecyl silane during the manufacturing process.
- the fine particles chemically modified in this way do not repel the moisture in the atmosphere, and thus can selectively capture chemical substances.
- the chemical substance collector of the present invention can be used as a collector for an air purifier for removing chemical substances in the air.
- the collector of the present invention has a fibrous form, a fiber (aggregate) supporting metal alkoxide fine particles is inserted into a hollow tube, and this is held in the hollow tube by a frit. Thereby, the collector can be fixed in the hollow tube. Therefore, it becomes easy to fix the fiber for collecting the chemical substance to the collection tube.
- the chemical substance collector of the present invention is a fiber in which metal alkoxide fine particles are supported on the surface thereof, and the flow path resistance of the liquid is smaller than that of the conventional product. Therefore, it is preferable for efficient collection of a target chemical substance in a dilute sample.
- the surface area of the chemical substance collector is large. Therefore, the amount (load) of the target chemical substance that can be retained in the diluted sample is very large, and the retention capacity is improved. Further, when the fine particles on the fiber surface are chemically modified, the retention ability is further improved.
- the fiber collector carrying the metal alkoxide fine particles of the present invention can be formed into a space-sparse state due to the characteristics of the fibrous form, and can be used for collecting a dilute target chemical component in a gas.
- the flow resistance of the collector becomes extremely small, so that it exhibits excellent performance as a collector that hardly causes a pressure loss in continuous suction of the gas sampler. It is also possible to handle large quantities of gas at once.
