Zero level air generatorIt is generally composed of an air pump/compressor, a pressure stabilization system, a pressure control system, a purification system, and a display system. The gas system adopts voltage stabilization and overvoltage protection devices to improve the stability of gas pressure and ensure the safety and reliability of the use of zero level air generators. Equipped with drainage and dust filtration devices, and using stainless steel gas storage tanks instead of carbon steel storage tanks, the purity of compressed air is greatly improved, which can meet the matching needs of imported and domestic gas chromatographs.

　　Zero level air generatorPerformance characteristics:

1. High purity output: It can generate zero level air with extremely low hydrocarbon content, such as the Praller zero level air generator, which can produce zero level air with less than 0.05ppm hydrocarbons, meeting the requirements of various high-precision instruments for gas source purity.

2. Stable traffic: It can provide stable traffic output according to actual needs.

3. Safe and reliable: It is a non high pressure container with an internal pressure much lower than that of a steel cylinder, and there is no risk of explosion or transportation. Simultaneously equipped with automatic detection and alarm functions for the host.

Selection considerations:

1. Flow demand: Based on the actual number of instruments used and gas demand, select a suitable zero order air generator with appropriate flow rate. If multiple gas chromatographs need to be supplied with gas simultaneously, a high flow model should be chosen.

2. Purity requirements: Different applications have different purity requirements for zero grade air. For example, some high-precision scientific research analyses may require a hydrocarbon content of less than 0.05ppm. Therefore, products that meet the purity standards should be selected according to specific needs.

3. Supporting equipment: Consider compatibility with existing instruments and equipment, air compressors, etc., and whether additional accessories such as air inlet secondary filters need to be selected.
