A method and apparatus for the detection of trace volatiles such as those produced by fungal decay of timber, comprising a sampling probe (), comprising a housing () and bored barrel () adapted removably to receive an SPME device () in which a coated tipped fiber () is guided within a needle sheath () into the barrel (), and a pump () is energized to draw a fluid sample over the fiber tip within the bore of the barrel. A motor () advances and retracts the SPME device () and its fiber () for a sample to be captured thereby and the captured sample is then released within an instrument having an array of gas sensors whereby any trace volatiles captured by and released from the coated fiber () may then be analyzed by computer software to produce a fingerprint for the location and identification of the presence of trace volatiles at a site into which the sampling probe is introduced. Thus, there is provided a robust device for the protective and easy introduction of an SPME fiber into a sampling environment where such devices conventionally could not be used.
