Problems solved by technology

This not only wastes sampling paper, but more importantly, the large sample inlet has many defects: first, the heat is not concentrated, and the heating efficiency is low, which affects the detection sensitivity of the instrument; second, the power consumption is large, the battery working time is shortened, and the battery needs to be replaced frequently , affecting the performance of the instrument
Its wiping device is also only suitable for the use of single sampling carrier, that is, each test must be taken from the storage device of the sampling carrier, and then installed, sampled and tested, which not only makes the sampling operation complicated, but more importantly, it is extremely It is easy to contaminate other unused sampling carriers, which poses a serious problem for the storage of sampling carriers

Abstract

The invention relates to a hand-hold wiping and sampling device, which is capable of continually sampling a carrier. The sampling device mainly comprises a hand-hold part and a wiping and sampling part, wherein the hand-hold part is a rectangle shell; the inside of the shell is provided with a continual sampling carrier storage; the lower end of the carrier storage is provided with a bottom cover; the upper end of one side of the carrier storage is provided with a sampling carrier outlet; the lower part of the wiping and sampling part is provided with an arc wiping and sampling surface; and a carrier sampling cutter is arranged on the front end of the wiping and sampling part. The sampling device can be mounted and use a folded continual sampling carrier, and can be used for multiple times by one-step mounting, so that the mounting operation of the sampling carrier is simplified, the chance for polluting the sampling carrier is reduced and the storage of the sampling carrier is convenient.

Description

technical field [0001] The invention relates to a wiping sampling device, in particular to a hand-held wiping sampling device used for collecting surface samples of objects when an ion mobility spectrometer detects explosives and drugs. Background technique [0002] At present, the explosives and narcotics detection instrument of ion mobility spectrometry technology is a fast, sensitive and portable on-site detection instrument. The instrument has been widely used in military and security inspection agencies, and can detect the presence of trace explosives, drugs, chemical poisons and other substances. [0003] When using ion mobility spectrometer to detect prohibited items, in addition to gas sampling (commonly known as smell), the most commonly used method is solid sampling, that is, first wipe the surface of the item with a sampling carrier (such as sampling paper), and remove explosives or drugs. The particles are collected on the sampling carrier, and then the sampling...
