Abstract: The disclosure relates to an apparatus for the analysis of biological liquid samples, the apparatus having a measurement chamber defining a sample volume with an inlet and an outlet; a fluid handling system adapted for feeding a liquid to the sample volume through the inlet and for removing the liquid through the outlet; a thermostatic sample heater device adapted for controlling a sample temperature of a liquid sample in the measurement chamber; and a processor unit. An analyte sensor output may be corrected on the basis of the initial temperature thus determined. A corresponding method for the analysis of biological liquid samples is provided. Furthermore, a method of performing a quality control procedure using the apparatus or the method is disclosed.

Abstract: The present invention relates in one aspect to an apparatus for the analysis of biological liquid samples, the apparatus comprising: a measurement chamber defining a sample volume with an inlet and an outlet; a fluid handling system adapted for feeding a liquid to the sample volume through the inlet and for removing the liquid through the outlet; a thermostatic sample heater device adapted for controlling a sample temperature of a liquid sample in the measurement chamber; and a processor unit. The processor unit is configured for determining an initial temperature of the liquid sample injected into the measurement chamber based on flow data from the fluid handling system and sample heating data from the sample heater device. An analyte sensor output may be corrected on the basis of the initial temperature thus determined. A corresponding method for the analysis of biological liquid samples is provided.
