Why are the oxygen levels different between chambers prior to my experimental run? - After switching on the O2k, air calibration has to be performed; otherwise the displayed concentrations may deviate from accurate concentrations. - » Oxygen calibration - troubleshooting«

Do you know that you can use the Titration-Injection microPump (TIP2k) to perform an instrumental O2 background on the O2k-sV-Module? - (1) By adjusting the dithionite concentration to 2.5 mM, the instrumental O2 background can be performed with the "BG Feedback" settings. - »O2k-sV-Module«
- (2) By adjusting the TIP2k setup with specific settings for the O2k-sV-Module, the instrumental O2 background can be performed in the O2k-sV-Module. - »O2k-sV-Module«
