FIELD: measuring equipment.
SUBSTANCE: group of inventions relates to methods and apparatus for detecting substances of interest. Thermal desorption apparatus is configured to detect a substance of interest in a sample. Apparatus comprises: a wand configured to support a swab, and a detector comprising an analyser arranged to detect a substance of interest. Wand is configured to couple to the detector such that thermal desorption of a sample from the swab provides a part of the sample to the analyser.
EFFECT: higher efficiency of detecting substances of interest in a sample.
