Leaky Chamber
Leaky chamber test
- When the leakage is so little that cannot be noticed in a short amount of time, we recommend to follow the Leaky chamber test below:
- Decrease the oxygen concentration down to ~ 50 ฮผM (using Dithionite or N2 injection)
- Let the O2k record overnight with the chamber closed and illumination switched off
- The oxygen concentration should decrease overtime due to the O2 consumed by OroboPOS as it is shown in the figure. In this case, the chamber is assembled properly.
- If the oxygen concentration increases over time, a reassemble of the chamber is needed.
- Text in discussion for the page:
- To exclude the existence of an unnoticed leak from the chamber, we recommend to follow the Leaky chamber test below - especially after chamber reassembly:
- Decrease the oxygen concentration down to ~ 50 ฮผM (using Dithionite or N2 injection).
- Record the O2k measurement overnight with the chamber closed and illumination switched off.
- The oxygen concentration should decrease overtime due to the O2 consumed by OroboPOS as it is shown in the figure below. In this case, the chamber is assembled properly.
- If the oxygen concentration increases over time, a reassemble of the chamber is needed.
