Abstract

A sampling component including a sampling body that can be electrically heated and an outer surface of which has a wiping sampling area to receive a sample; and an insulated handle that is connected to one longitudinal end of the sampling body. The sampling component contacts directly electrical contacts of an external power supply after being positioned in a analysis chamber, the power supply is turned on to vaporize the sample, and the power is turned off immediately after the sampling component removed from the chamber. The power consumption and a malfunction caused by long-term use of the sampling device under a high temperature can be avoided. A sampling device having the sampling component and an ion mobility spectrometer having the sampling device are also provided.
