TRACE GAS SAMPLING DEVICE AND DETECTION SYSTEM

Provided are a trace vapor sampling device and a detection system. The trace vapor sampling device includes: a moving carrier (1); a plurality of sampling apparatuses (2) provided on the moving carrier (1), including: a sampling hose (21) configured to go deep into an inside of a target to be inspected, the sampling hose (21) is configured to acquire a target vapor inside the target; a sampling channel (22) connected to the sampling hose (21) and configured to transmit the target vapor; and an pre-concentrator (23) provided in the sampling channel (22), an adsorption medium (24) is placed inside the pre-concentrator (23), and the target vapor is adsorbed onto the adsorption medium (24); a control apparatus (3) provided on the moving carrier (1); and at least one air pump (9), each air pump (9) is controllably communicated with one or more sampling apparatuses (2), the control apparatus (3) controls each air pump (9) to be selectively communicated with one sampling apparatus (2) or one of the plurality of sampling apparatuses (2), so that the air pump (9) drives the sampling hose (21) of the communicated sampling apparatus (2) to acquire the target vapor. The detection system includes the trace vapor sampling device and an analysis device. The analysis device is configured to inspect and analyze the target vapor acquired by the sampling device or the adsorption medium (24) adsorbed with the target vapor so as to obtain an analysis result.
