ABSTRACT:
In a method of photometric in vitro determination of the content of oxygen in a blood sample, a blood sample is transferred directly from an in vivo locality to an at least partially transparent sample container of a sampling device. The sample container has a measuring chamber containing a luminophor, the luminescence of which is quenched in the presence of oxygen. The luminophor is excited by irradiation with radiation from a radiation source. The luminescence emitted by the excited luminophor is detected by a radiation detector and the oxygen content determined on the basis of the radiation detected by the radiation detector. A sampling device and a system for photometric in vitro determination of oxygen in a blood sample are also described.
