Sparging with N2
Sparging with N2
Method: Injection of N2 to achieve anaerobic environment
- Procedure
- Put carefully one long needle in the vessel for injecting N2
- Put one short needle in the vessel for removing the containing oxygen
- Open the pressure valve of the Nitrogen gas container
- Turn round (anticlockwise) the nitrogen valve to open it until there is a flow of gas.
- Sparge with N2 by connecting the N2 gas tube with the long needle.
- After 3/ 5 min remove first the small needle and after 2 seconds the long needle.
- Turn off the nitrogen valve.
- Turn off the pressure valve.
