Abstract
The application relates to a closing element for closing a container for samples for analysis, particularly biological samples. The application also relates to an assembly of a container and a closing element connected to the container. The application also relates to a device and method for analysing samples. The closure comprises a vent channel (6) with a bacterial filter (7), a penetrable element (5) and the vent channel is configured to be connected with an analyser and can be opened and closed.

A closing element for closing a container for samples for analysis, particularly biological samples, comprising:
- at least one penetrable element for injecting a sample via the closing element into a container connected to the closing element, and
- at least one ventilating channel provided with at least one bacterial filter, which bacterial filter is substantially impermeable to bacteria and is at least permeable to at least one metabolic gas formed in the biological sample, which ventilating channel is configured for connection to a device for analysing metabolic gas,
- wherein the at least one ventilating channel is closed in substantially unloaded state by another part of the closing element, in particular a closing body of the closing element, and wherein opening of the ventilating channel takes place by loading at least a part of the closing element.
A method for analysing samples, particularly biological samples, by making use of an assembly of a container for a biological sample and a closing element connected to the container, comprising the steps of:
- A) providing an assembly of a container and a closing element connected to the container,
- B) injecting a biological sample via at least one penetrable element of the closing element into the container,
- C) having at least one ventilating channel of the closing element connect in substantially medium-tight manner to at least one analysis compartment provided with at least one chemical trace detector,
- D) allowing metabolic gas formed in the container to displace via the ventilating channel and a bacterial filter of the closing element into the analysis compartment, and
- E) at least partially analysing the metabolic gas in the analysis compartment with at least one chemical trace detector.
