| 摘要 |
The invention relates to an oximeter for spectro-photometric in-vitro determination of hemoglobin derivatives in a sample, preferably a hemolyzed blood sample, with a single measurement light source emitting measurement radiation, and with a sample chamber, for instance a measurement cuvette containing the sample, and with a detector device, which records a spectrum of the measurement radiation after its interaction with the sample, and with an evaluation unit following the detector device, which determines the hemoglob in derivatives and at least one further analyte from the spectrum recorded by t he detector device. According to the invention the measurement light source is a polychromatic LED, which for determination of hemoglobin derivatives emits measurement radiation in at least one spectral region B, in which the hemoglobin derivatives exhibit significant absorbance, and which for determination of a t least one further analyte emits measurement radiation in at least one other spectr al region A, in which the at least one further analyte exhibits significant absorbance.
