The assembly of the chamber and a procedure to position the glass chamber very accurately is described in MiPNet12.06. A wrongly positioned glass chamber can lead to a huge variety of problems, some obvious but others very difficult to understand.
Possible Problems
- chamber leaking liquids (medium is leaking out of the chamber)
- oxygen leak of the chamber (strongly negative intercept in the instrumental background test
- unstable O2 signal
- unexpected high or low O2 signal
Trouble shooting procedure
If the problem is obviously related to the chamber proceed to solutions.| Otherwise follow Locating a problem If the problem is not located on the POS or the POS connector try solving the problem by reassembling the chamber before concluding that the main unit is defect.
Solutions
- Disassemble the chamber by reversing the instructions in MiPNet19.18A O2k-Start.
- Check for visible damages on the glass chamber, on the POS seal tip and all o-rings (on chamber holders or on stoppers). If a damage is visible replace the part or consult OROBOROS Instruments. If there is a deposit visible in the glass chamber see Cleaning the glass chamber.
- Reassemble the chamber following exactly the description in MiPNet19.18A O2k-Start. Especially, use only small increments (not more than successive quarter turns of the POS holder) when lowering the chamber.
