Talk:O2k-Open Support alert

In discussion for page

Do you perform the leaky chamber test after chamber assembly?

After chamber reassembly you might experience a small leaky chamber only identified by a leaky chamber test- »Leaky chamber test«

Do you know that you can use the Titration-Injection microPump (TIP2k) to perform an instrumental O₂ background on the O2k-sV-Module?

By adjusting the dithionite concentration to 2.5 mM, the instrumental O₂ background can be performed with specific settings for the O2k-sV-Module. - »O2k-sV-Module«

Do you know how the "switch components" approach can guide you to find what is causing your O2k not to reach the required specifications?

Do not desperate if specifications given in the O2k-Manuals are not obtained. See how to perform an experimental troubleshooting on your own.-»Switch components approach«

Do you know that a humid O2k-environment and/or liquid spillage may lead to a high raw POS signal [V]?

See how to clean and dry the electrical connections of the OroboPOS-Connector.-»Cleaning the electrical connections«

O2k-Open Support alert circulars

O2k-Open Support alert circular 2020(01): in prep

New A damaged OroboPOS-Holder may cause medium to leak from the O2k-Chamber.

See how you can check that the two blue OroboPOS-Holders are intact. - »O2k-OroboPOS-Holder«

New Calibration parameters are transferred to experimental DatLab files

Save calibration information from selected Marks while DatLab is connected to the O2k during an instrumental calibration run. Air calibration and zero oxygen calibration can be performed and saved in a single DatLab file or in separate DatLab files. - » Oxygen calibration - DatLab«

Do you perform O2k-Chamber volume calibration?

The volume calibration is essential to ensure that the chamber volume is correctly calibrated to its standard volume of 2 mL (or 0.5 mL for the O2k-sV-Module). - »O2k-Chamber MitoPedia«

Do you use the correct O₂ solubility factor (F_M) in the ‘O2 calibration’ window in DatLab?

The O₂ solubility factor varies according to the medium used and influences the air calibration. - »Oxygen solubility factor«
