1. A sample collector for receiving a breath gas sample to be investigated, the sample collector comprising:
an inflow part with an inflow opening; and
an outflow part with an outflow opening, the outflow part comprising a separator element and a supporting element;
a collector casing, wherein:
the sample collector provides a flow duct guiding a gas sample from the inflow opening to the outflow opening;
the inflow part and the outflow part together form a housing which gas-tightly surrounds the flow duct;
the collector casing surrounds the housing such that a dead space is provided between the collector casing and the housing;
the separator element bridges a distance between the housing and the collector casing and forms one wall of the dead space;
the supporting element engages an inner side of the collector casing;
the inflow part tapers in a direction towards the outflow opening; and
the outflow part tapers in a direction towards the inflow opening.
