Sample collector for receiving a breath gas sample and gas sample testing device

A gas sample testing device comprising:

• 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, wherein 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;
• and
• a base body, the base body comprising a gas sensor, wherein:
• the sample collector is mechanically connected with the base body;
• the outflow opening of the sample collector points towards the base body;
• the sample collector is configured to guide a received gas sample towards the base body;
• and
• the gas sensor is configured to detect at least one substance in a received gas sample.
