Redesigned apparatus for anaerobic measurement of blood pH at low temperatures.

A newly designed apparatus for anaerobic measurement of blood pH at low temperatures is presented. This apparatus features a larger glass electrode surface area, which is necessary to overcome the increased resistance of the glass as blood pH determinations at 0-15 C. are undertaken. Utilization of this equipment has confirmed the deltapH per degree C. of whole blood to be 0.0156, while intracellular pH of blood has a deltapH per degree C. of 0.0165.
