PROCEDIMENTO ED APPARECCHIATURA PER LA DETERMINAZIONE ELETTROCHIMICA DI O2 IN UN EMOGASANALIZZATORE.

摘要

In a blood gas analyzer, a substantially oxygen-free measurement solution is fed through a measuring cell (17) as far as a diffusion cell (13) in which the measurement solution is brought into contact with the blood sample to be tested. When the gases dissolved in the sample have diffused through the membrane (12), the measurement solution is propelled in the reverse direction within the circuit to feed into a measuring cell (17) the measurement solution which had remained static in the diffusion cell (13), to then measure the value of an electrical quantity related to the pO2.
