Abstract

This invention focuses on the development of a gas catcher that can be used to capture gases for analysis. Chemical content or used in direct gas analysis For high efficiency in gas capture Increase efficiency in Capture of gases as it passes and drains And reduce the gas leakage caused by the test It also works It is convenient, fast and inexpensive as well. A gas catcher used for chemical analysis. Consists of a gas feeder and a gas catcher And gas vent In which the components are connected sufficiently To allow the gas to flow through the perforated cavity to vent without leaking to the side by means of a screw fixed by the gas catcher, it can be used for direct chemical analysis and gas analysis. Which must first make Gas is generated in the gas feeder vessel prior to analysis. The second type is achieved by connecting the gas feed and vent to a cylindrical tube with both open ends and through holes. Allowing gas to pass through a cylindrical tube allowing gas to pass through all three Where the open end of such cylindrical tube may be connected to A gas extractor for gas transmission at the desired speed. In both cases The gas catcher can capture many gases. The type can be hierarchical in a single gas transmission.

Claims (4)

1. Gas capture apparatus consists of - Gas feeder (1) that looks like a container (4) is a flask or cylindrical container that It has one end as an open end and is covered with a cap (5) that is either a flat cap or a cover and the other is a closed end. The top of the cap (5) is connected to the gas catcher (2), and the cap (5) has a through hole that forms a gas vent. That can drain the gas from the gas feeder (1) to the gas trap (2). The gas vent is smaller than the diameter of the cover (5) but has a width that Suitable enough for the gas to escape from the gas feeder (1) - the gas catcher (2) is connected to the top of the cover (5) of the gas feeder (1) to the gas catcher (2). It consists of a gas catcher (6) and an elastic pad (7) placed alternately at least one layer on the cover (5) of the gas feeder (1). The elastic pad (7) is flat and flexible. There are holes through the hole to drain. The gas capture plate (6) is available and the gas trap (6) is a small porous paper sheet that can provide Diffuse gas The gas catcher (6) covers the perforated opening of the elastic plate (7), the gas that spread through the gas catcher (6) can continue to be discharged to the gas vent (3) - The gas vent (3) is a flat plate (8) which is placed over the top of the gas capture plate (6) of the gas catcher (2). The flat plate (8) has a perforated hole to provide a A vent for releasing gases from the gas catcher (2) into the atmosphere, the flat plate (8) is similar to the elastic plate (7) but with a harder material. The characteristics are the gas feeder (1), the gas catcher (2) and the gas vent (3), the three are connected tightly enough to allow the gas to flow through the penetrating port to vent without allowing Leaked out to the side by means of mounting screws (9), where elastic pads (7) made of a choice of silicone, rubber or plastic material will help the three connect very tightly together. Even more The gas vent holes of the three above are consistent in size and position. The diameter is in the range of 2-5 mm. It is suitable for the reaction of vented and diffused gases through a gas capture plate (7) that is saturated with a gas trap. The types of detectors can be selected independently of each gas capture plate. 2. The gas catcher according to claim 1, which has an additional feature, is the connection of a container (10) or a cylindrical tube (11) of both open ends to the gas catcher. It is connected to the closed end of the gas feeder (1) and provides a perforation hole so that the gas can be vented through a container (10) or a cylinder (11) to the gas feeder (1), or connected. With the top of the flat plate (8) of the gas vent (3), as a result, the gas can be vented externally through the gas feeder (1), the gas catcher (2), the gas vent (3) and discharged into the atmosphere. 3. Gas capture apparatus according to claim 1 or 2, in which the mouth of the container (4) of the gas feeder (1) is additionally assembled. With a flexible sheet placed over the mouth of the container (4) before sealing the container with a lid (5) 4. Gas catcher according to one of the 1-3 claims. Which contains additional cotton swabs impregnated with gas detectors Interference for use in the interfering gas that occurs before the gas capture with a gas catcher. It is placed in the container (4) of the gas feeder (1).
