...Michael Oellermann; Hans-O. Pörtner; Felix C. Mark Oxygen equilibrium curves have been widely used to understand oxygen transport in numerous organisms. A major challenge has been to monitor oxygen binding characteristics and concomitant pH changes as they occur in vivo , in limited sample volumes...

... results are based on 42 oxygen equilibrium curves. Oxygen equilibrium curves were determined spectrophotometrically using a diffusion chamber ( Sick and Gersonde, 1969 ; modified by Bridges et al . 1979 ). The O2 tensions in a 10 μ l sample were varied using gas-mixing pumps (303 a / f Wösthoff...
