Patent ID: 7710550

Claim:
An oximeter for spectro-photometric in-vitro determination of hemoglobin derivatives and at least one further analyte in a sample comprising: a single measurement light source, which emits measurement radiation, being directed to a sample chamber containing a sample, a detector device, which records a spectrum of the measurement radiation after its interaction with said sample, and an evaluation unit following the detector device, which determines the hemoglobin derivatives and at least one further analyte from the spectrum recorded by the detector device, wherein the measurement light source is a polychromatic LED, which for determining the hemoglobin derivatives emits measurement radiation in at least one spectral region B in which the hemoglobin derivatives exhibit significant absorbance, and which for determining said at least one further analyte emits measurement radiation in at least one other spectral region A in which the at least one further analyte exhibits significant absorbance.
