Method of photometric in vitro determination of the content of oxygen in a blood sample

DETAILED DESCRIPTION The object of the invention is to provide an in vitro method for determination of the content of oxygen in a blood sample, the method being more appropriate for the user in that there is obtained both a more simple and less risky sample handling and a more simple maintenance of the oxygen analyzer utilized in practising the method.
This is achieved by the method according to the invention, comprising transferring a blood sample from an in vivo locality to the sample container of a sampling device, the sample container having a measuring chamber with an at least locally transparent wall part and containing a luminophor; breaking the connection between the sampling device and the in vivo locality after filling the sample container with the blood sample; bringing the measuring chamber into optical communication with an optical system comprising a radiation source and a radiation detector; exciting the luminophor within the measuring chamber by irradiation with radiation from the radiation source; and determining the luminescence characteristic of the luminescence emitted from the luminophor based on the luminescence detected at the radiation detector.
