Which medium can be used for the instrumental background test?

When using dithionite, the instrumental background test should be performed in mitochondrial respiration medium MiR05, MiR05-Kit or MiR06; or alternatively, in a strong alkaline phosphate buffer (>100 mM; >pH 8), to avoid side reactions that might interfere with the test.

Do you observe an unstable O₂ slope negative following TIP2k titrations during an instrumental O₂ background test?

Incorrect placement of TIP2k Filter Papers can lead to liquid accumulation and convective oxygen backdiffusion. Check for proper placement by confirming they are fully in contact with the stopper receptacle.

What to do if the glass of the O2k-chamber starts to become opaque?

"Turbidity on the glass wall may be caused by precipitated protein. Remove the chambers from the O2k and with the O2k-stirrers removed, immerse in a beaker filled with HCl (10 M) overnight under a hood."

Can I use the same stock solutions for all reagents for different O2k-chamber volumes?

"For some reagents, the concentration of the stock solution differs between the 2.0-mL and the 0.5-mL chamber (O2k-sV-Module) to facilitate a precise volume titration."

How do I view and change the settings of a measurement/file in DatLab 8?

"O2k control (active) will always show the settings of the active recording [and allow changes], while O2k info (view) will show the settings of the recorded selected file."
