In an example, a sample collection apparatus to collect sample from a detection subject includes a circumferential ring tubing surrounding an interior and configured to be moved between bottom ring tubing position and top ring tubing position. The circumferential ring tubing includes air nozzles along a circumferential length of the ring tubing to direct air flow toward the interior as the ring tubing is moved from the top ring tubing position to the bottom ring tubing position, to blow air toward the detection subject in a sample collection zone in the interior and to push a sample of the detection subject via an air flow toward a platform on which the detection subject is positioned. The sample includes particles and/or vapor of the detection subject. A receptacle is disposed below the platform to collect the sample carried by the air flow through collection openings of the platform to the receptacle.
