| === 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 ΞΌM (using [[Dithionite]] or N<sub>2</sub> injection)
| |
| ::::# Let the O2k record overnight with the [[closed chamber|chamber closed]] and illumination switched off
| |
| ::::# The oxygen concentration should decrease overtime due to the O<sub>2</sub> consumed by [[OroboPOS]] as it is shown in the figure. In this case, the chamber is assembledΒ properly.
| |
| ::::# If the oxygen concentration increases over time, a reassemble of the chamber is needed.

| ::::* 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 ΞΌM (using [[Dithionite]] or N<sub>2</sub> injection).
| |
| ::::# Record the O2k measurement overnight with the [[closed chamber|chamber closed]] and illumination switched off.
| |
| ::::# The oxygen concentration should decrease overtime due to the O<sub>2</sub> consumed by [[OroboPOS]] as it is shown in the figure below. In this case, the chamber is assembledΒ properly.
| |
| ::::# If the oxygen concentration increases over time, a reassemble of the chamber is needed.
