Product Details
Stream membrane separation nitrogen generator
The development of membrane nitrogen generators aims to meet specific requirements for flow rate, purity, and pressure in LC-MS applications. It can also be used to analyze the evaporation of solvents in samples.
Simple and efficient membrane technology enables the separation of other components at the compressed air inlet from nitrogen gas, resulting in high-purity nitrogen gas.
Technical Specifications
Intake pressure: 13 bar
Exhaust pressure: 7 bar
Dew point: -40 ℃
Exhaust purity:>99%
Power requirement: None
Noise: No mechanical component movement
Daily maintenance: Replace the gas filter once a year
Three modes:
-Stream-40 maximum flow rate 40L/min
-Stream-80 maximum flow rate 80L/min
-Stream-120 maximum flow rate 120L/min
Details
Improve instrument performance
The stable flow rate of high-purity nitrogen generated improves the stability of instrument operation and ensures high reproducibility of detection results.
Improve laboratory work efficiency
The wall mounted nitrogen purification device generates continuous and high flow of nitrogen, which meets the requirementsLC/MSTo meet the application requirements, it avoids interrupting the operation of the instrument due to a lack of nitrogen gas.
cost saving
No need for nitrogen tanks and nitrogen delivery pipelines, saving storage space for nitrogen.
高安全性
The wall mounted nitrogen purification device generates nitrogen at room temperature and low pressure, avoiding the potential hazards of using high-pressure nitrogen cylinders and liquid nitrogen.
Easy installation
The wall mounted nitrogen purification device is easy to install, saves laboratory space, and does not require a power socket connection.
membrane separation technology
Membrane separation technology forces compressed air through hollow fiber membranes, selectively permeating nitrogen, oxygen, carbon dioxide, water vapor, and trace inert gases according to different diffusion coefficients. The diffusion coefficient of nitrogen in hollow cellulose membranes is slower than that of other gas components. Other gases flow out of the cellulose membrane, leaving only nitrogen in the membrane, thus achieving separation.
