A device for taking a sample of breath has a tubular body 10 with a piston 12 inserted into a first end thereof, a first port 18 formed through a side wall and a second port 16 formed at or adjacent a second end. The first port 18 or the second port 16 provides an inlet for receiving a breath sample and the second port 16 provides an outlet through which the breath sample may subsequently be discharged from the tubular body. The second part is typically coupled to a sample tube 20 housing an adsorbent 22 for any volatile compounds present in the breath sample when it is expelled from the sampling device by depression of the piston 12 into the tubular body 10. The sample tube 20 may then be subjected to analysis. |
