Example Embodiment

[0024] The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0025] As attached Figure 1 to 3 As shown, the specific steps of a method for continuously providing sampling carriers of the present invention are:

[0026] Firstly, the sampling carrier 4 is cut into a sheet-like long strip, the width of the strip is slightly narrower than the injection port of the ion transfer device, and the length should satisfy dozens or hundreds of sampling times. Fold it back and forth into several layers (similar to old continuous printing paper) according to the length of the single piece of sampling carrier 1 or its multiples (depending on the length of the sampler). At this time, the effective sampling part of the sampling carrier 4 is straight. When one end is pulled out, the sampling carrier can still remain straight.

[0027] Then, make installation or cutting marks or cutting lines on the sampling carrier strip, and ext...

Abstract

The invention provides a method and a device capable of continuously providing a sampling carrier, which are used for a hand-held wiping sampler. In the invention, the sampling carrier is manufactured into a long-strip shape, is folded into a layer shape according to certain length and sealed into a storage box, wherein one end of the storage box is provided with an outlet. A sampling carrier box is arranged on a special sampler, is pulled out for proper length to be fixed on a wiping surface when sampling, and a sample part is cut off for detection after the sampling. The continuous sampling carrier can keep straight and cannot be polluted in the processes of storage and application, is capable of sampling for multiple times by one-step mounting, simplifies the wiping sampling operation and improves the service efficiency of an ionic migration spectrometer.

Description

technical field [0001] The invention relates to a method and a device for continuously providing sampling carriers. Background technique [0002] At present, the explosives and drug detection device of ion mobility spectrometry technology is a fast, sensitive and portable on-site detection device. The device has begun to be used in military and security inspection agencies, and can detect explosives, drugs, chemical poisons and other substances. [0003] When the ion mobility spectrometer detects prohibited items, in addition to the gas sampling (commonly known as smell) method, the most commonly used method is the solid sampling method. That is, first wipe the surface of the object with a sampling carrier (such as sampling paper), collect explosives or drug particles on the sampling carrier, and then insert the sampling carrier into the inlet of the detection device for detection and identification. In order to avoid contamination of the sampling carrier, the sampling car...
