Abstract
A nitrogen and clean air generator comprises an air source, a filter and pressure regulating valves, which is characterized in that the air source is sequentially connected with the filter and a divider pipe inlet, the divider pipe outlet is connected with a nitrogen passage, a zero air passage and a clean air passage respectively, the nitrogen passage is equipped with a nitrogen separating membrane component and a pressure regulating valve, the zero air passage is equipped with an air drying pipe and a pressure regulating valve, and the clean air passage is equipped with a pressure regulating valves. The nitrogen and clean air generator has the advantages that stability of instrument analysis and reproducibility of results can be effectively increased due to continuous and stable gas supply, gas supply is safe because nitrogen is produced in low pressure with overpressure suppression, manually moving and operating a high pressure steel cylinder is avoided, and safety hazards are reduced, further the nitrogen and clean air generator has simple installation, low cost, simple operation, high membrane component separating accuracy and long service life.
Description
Technical field
The utility model relates to a kind of for the nitrogen pure air generator of the supporting air feed of liquid chromatograph-mass spectrometer analytical test coupling.
Background technology
Often will use various sources of the gas in the Laboratory Instruments analysis, (LC/MS) is widely used in fields such as biological chemistry, medical research and application, environmental analysis, food analysis and clinical practice as liquid chromatograph mass spectrography.The traditional experiment chamber normally adopts lower steel cylinder of purchase cost or high pressure gas holder to realize to the plenum system of LC/MS, but because of himself air-capacitor quantitative limitation, laboratory work person has to order continually, carries, installs and changes steel cylinder (high pressure gas holder), this not only expends great amount of manpower and material resources and time, even makes some important experimental works be forced to interrupt; The interim automatic deflation pressure reducing protection of high pressure gas holder is a kind of inevitable technological deficiency, has also directly caused the unnecessary waste of user's gas resource; And steel cylinder and Dewar flask nitrogen under the situation of the no obvious sign of being everlasting is used up, thereby causes the experiment of user's important analysis to be forced to stop.
The utility model content
The purpose of this utility model is: provide a kind of easy to use, safe efficient, be the nitrogen pure air generator of the supporting air feed of liquid chromatograph-mass spectrometer analytical test coupling.
For achieving the above object, the technical scheme that adopts is: a kind of nitrogen clean gas generator, comprise air source of the gas, filtrator and pressure regulator valve, it is characterized in that: described air source of the gas is connected successively with the import of filtrator, isocon, the outlet of described isocon is connected with nitrogen, zero level air, each gas branch road of pure air respectively, described nitrogen branch road is equipped with nitrogen separation membrane module and pressure regulator valve, described zero level air branch road is equipped with air drying pipe and pressure regulator valve, and described pure air branch road is equipped with pressure regulator valve.The filtrator that is connected with the air source of the gas is a multistage filter: earlier 0.1 μ m filters, 0.01 μ m filters, activated carbon filtration again.
Between gas drying tube and the pressure regulator valve, also can be equipped with filtrator as required in the described nitrogen branch road between nitrogen separation membrane module and the pressure regulator valve, in the described zero level air branch road.The filtrator that is equipped with is 0.01 μ m filtrator in the described nitrogen branch road and in the zero level air branch road.
The beneficial effects of the utility model are:
A. continuously, stablize air feed, effectively improve the stable and result's of instrumental analysis reproducibility;
B. low pressure produces nitrogen, overpressure protection, and air feed safety need not manually-operated, carrying high-pressure cylinder container, reduces potential safety hazard;
C. installation is easy, cost is low, simple to operate, can produce high-purity nitrogen after the installation, and the air feed expense is low, and is economical and practical, need not artificial supervision, improves the LC/MS service efficiency;
D. membrane module separation accuracy height, long service life.
