Abstract: A sample cell for IR spectrophotometric analysis of a liquid sample is provided. The sample cell comprises two substantially parallel transparent plates enclosing a cavity for holding the liquid sample, and a temperature control loop for controlling a temperature of the liquid sample in the cavity. The temperature control loop comprises at least one temperature sensor for measuring a temperature in or close to the cavity, at least one heating element for increasing a temperature of the liquid sample, and control means, coupled to the temperature sensor and the heating element for controlling the heating element in dependence of the temperature in or close to the cavity. The heating element comprises at least one heating foil which is attached to or thermally coupled to a first one of the transparent plates in such a way to allow an IR light beam to pass through the transparent plates and the cavity without being hindered by the heating foil.
