Abstract
The utility model relates to a gas-path adapter, which comprises a gas-path pipe connecting-end joint and a chromatograph connecting-end joint, wherein a polytetrafluoroethylene gasket is arranged at the connecting part of the inside of the chromatograph connecting-end joint and the gas-path pipe connecting-end joint, a screw cap is installed on the gas-path pipe connecting-end joint, external threads are arranged outside the gas-path pipe connecting-end joint, and internal threads are arranged inside the chromatograph connecting-end joint. Through the gas-path adapter disclosed by the utility model, a gas-source inlet of a Shimadzu gas chromatograph can be connected with a copper pipe, a stainless-steel pipe and a polytetrafluoroethylene pipe having any length and outside diameters being 1/8 inch or 3mm, and the gas-path adapter is convenient for the installation and the use of instruments.
Description
Technical field
The utility model relates to gas composition analyzing and testing apparatus field, relates in particular to be connected with the gas circuit pipe gas circuit adapter of usefulness of a kind of chromatograph.
Background technology
Gas chromatograph (GC) is used very wide at aspects such as oil, chemical industry, biological chemistry, medical and health, food industry, environmental protection, it is except that being used for quantitative and qualitative analysis, can also the physicochemical constants such as partition factor, activity coefficient, molecular weight and specific surface area of working sample on stationary phase, be a kind of to each is formed and divides the instrument that carries out analyzing and testing in the mixed gas.
Day, island proper Tianjin founding of the company was in 1875, so far have the history in more than 100 year, first commercial gas chromatograph GC-1A in Japan, be exactly that Tianjin, island company produces, its analytical instrument product begins to enter China market after therefrom establishing diplomatic relations day, with an American-European relatively line brand analytical instrument near 50% price advantage, occupied the suitable market share in China.In recent years along with Tianjin, island company in Hong Kong and Shanghai incorporation, and set up international production line in Suzhou, serial gas chromatographies such as GC-14, GC-2014 have realized " localization ", make it become the GC type that Chinese user is familiar with the most.Inexpensive corresponding with Tianjin, island GC, the particularization of its related accessory and consumptive material is then very troubling, and especially the associated line of gas chromatograph and source of the gas adopts special umbrella cover shape metal joint, and the standard configuration pipeline only has five meters, and price is also relatively more expensive.1/8 inch of general in the world external diameter all can not directly be connected with the gas chromatograph of Tianjin, island company with 3mm gas circuit pipe, for the installation and the use of instrument are made troubles.
Summary of the invention
In order to solve the problem that island functional activities of the body fluid chromatography can't be connected with international gas circuit pipeline, the utility model provides a kind of gas circuit adapter.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of gas circuit adapter, comprise gas circuit pipe link joint and chromatograph link joint, chromatograph link joint is inner to be provided with the tetrafluoro packing ring with gas circuit pipe link joint junction, on the gas circuit pipe link joint nut is installed.
Gas circuit pipe link joint outside is provided with external thread, and chromatograph link joint inside is provided with internal thread.
Gas circuit adapter of the present utility model can be connected the air source inlet of island functional activities of the body fluid chromatography with copper pipe, stainless-steel tube, the four fluorine tube of 1/8 inch of random length external diameter or 3mm, is convenient to the installation and the use of instrument.
Description of drawings
Fig. 1 is the structural drawing of the utility model gas circuit adapter.
Fig. 2 is the nut structure figure of the utility model gas circuit adapter.
Embodiment
Gas circuit adapter of the present utility model is to design a kind of metal adapter for island functional activities of the body fluid chromatography air source inlet, comprise gas circuit pipe link joint 1 and chromatograph link joint 3, chromatograph link joint 3 inside are provided with tetrafluoro packing ring 2 with gas circuit pipe link joint 1 junction, and nut 4 is installed on the gas circuit pipe link joint 1.
Gas circuit pipe link joint 1 outside is provided with the external thread of M8 * 1mm, and chromatograph link joint 3 inside are provided with the internal thread of M10 * 1mm, and central authorities are the hole of 3mm, and pipeline can directly insert.
The beneficial effects of the utility model are that the air source inlet of Shimadzu gas chromatograph can be connected with copper pipe, stainless steel tube, the four fluorine tube of 1/8 inch of random length external diameter or 3mm, are convenient to installation and the use of instrument.
