| titleOfInvention | COMBINED CAPILLARY DISPENSER OF STEAM-GAS MIXTURES |
| abstract | Combined capillary dispenser of steam-gas mixtures refers to the field of analysis of materials by determining their chemical and physical properties, specifically to obtain or prepare samples for research by diluting, spraying or mixing them. The objective of the utility model is to obtain stable for a long time gas-vapor mixtures of microconcentrations of substances with high volatility. The technical result that can be obtained using the utility model is to develop a combined dispenser for creating vapor-gas mixtures of microconcentrations of substances with high volatility, with operational control of changes in their physicochemical properties during the dosing process, as well as the amount of dosed substance per unit time. The problem is achieved in that the dispenser consists of an evaporator chamber, a diffusion chamber and a mixing chamber. At the same time, a permeable membrane made of polyethylene is additionally inserted into it, rigidly fixed to a replaceable nozzle with a capillary located in the area of the neck of the glass vial with the metered substance and forming a detachable connection with it, as well as dividing its internal volume into two chambers: evaporative and diffusion . The device of the combined dispenser of gas-vapor mixtures allows you to visually control the change in the properties of the substance during the dosing process. The amount of dosed substance per unit time is determined by the parameters of the installed permeable membrane and capillary, which does not require disassembly and subsequent assembly of the dispenser. To create a vapor-air mixture with a given concentration with other dosed substances, it is necessary either to connect another vial with this substance or to fill in a new dosed substance in the existing vial, while replacing the nozzle with the permeable membrane and capillary required for this substance. The advantage of the proposed combined dispenser is the ability to create gas-vapor mixtures of microconcentrations of substances with high volatility, with the ability to promptly and qualitatively control both changes in the properties of the substance during the dosing process and the amount of dosed substance per unit. 1 ill. |
