Abstract
A method of photometric in vitro determination of at least one blood gas parameter in a sample of whole blood. The whole blood sample is obtained by connecting an at least partially transparent sample container to an in vivo locality and transferring whole blood into the sample container, then breaking the connection. The sample container is arranged in an optical system which has a radiation source and a means for detecting radiation to locate the sample container between the radiation source and the radiation detection means. Radiation is transmitted to the sample from the radiation source and radiation emitted from the sample is transmitted to the radiation detection means. The detected radiation is used to determine the blood gas parameter of the sample. A system for use in this method has a radiation source, a radiation detection means, an at least partially transparent sample container, and a sample container station.
