A portable apparatus (10, BACT) to be used to sample and analyze volatile organic compounds (VOCS) in breath air, comprising: - a box (1) that is divided at the inside in two internal sections (2, 3) each housing a sample collecting tube or filter (4, 5) in turn containing a stationary phase (16) suitable for retaining determined analytes, as drugs and/or respective metabolites, having specific chemical physical properties, contained in breath air - a breath pre-accumulation chamber (18) for receiving the breath air from the outside through a breath entrance connection (6) and for feeding the received breath air to the sample collecting filters (4, 5) housed in said two internal sections (2, 3), with these two sample collecting filters (4, 5) being connected in parallel to said chamber (18) and - a tool application kit (15, 22, 23) for removing the two sample collecting filters (4, 5) from the respective sections (2, 3) in the box (1) of the apparatus (10), in a way that avoids any contamination of them, and for extracting the analytes that are retained by the stationary phase (16) on the same two sample collecting filters (4, 5), wherein, in the event of a positive detection of drug in a first filter (4), of said two sample collecting tubes or filters (4, 5), analyzed by using said tool application kit (15, 23), also the second filter (5) of said sample collecting filters (4, 5) is analyzed, in particular by using a gas chromatography-mass spectrometer (GC-MS) or a liquid chromatography-mass spectrometer (LC-MS), in order to confirm the results of the analysis performed on the first sample collecting filter (4). The sampling and analyzing apparatus of the invention is particularly suitable for executing road drug tests, in compliance with the requirements and the needs of the procedure of the police that has to perform these drug tests.Linvention porte sur un appareil portatif (10, BACT) destiné à être utilisé pour échantillonner et analyser des composés organiques
