Wipe sampling assembly
A wipe sampling assembly used for an ion mobility spectrometer is disclosed. The wipe sampling assembly comprises three layers in which the upper layer and the lower layer are protective paper sheets, while the middle layer is a sampling swab. The swab will not be contaminated when not in use as it is covered by the two protective paper sheets. The hand can only contact the protective paper and will not contact the swab while sampling to prevent the swab from being contaminated. The above wipe sampling assembly is used with no need for any additional device, thus making it easy to operate and carry.
