Abstract
Disclosed is a device for continuously supplying sampling carrier, which is used for a hand-held wiping sampler. The sampling carrier is made into a strip type, and folded into layers in certain length, and then sealed into a storage box, at one end of which an outlet is arranged. A sampling carrier box is arranged on a special sampler, during sampling, a certain length of the sampler is pulled out and fixed on the wiping surface, and after being sampled, the sampling part is cut off and taken off for test. The continuous sampling carrier can keep flat and straight, and is free of pollution during storage and use, the multiple-sampling is performed after installation, the wipe sampling operation is simplified, and the service efficiency of an ion mobility spectrometer is improved.
Description
Technical field
The utility model relates to a kind of method and apparatus that sampling carrier can be provided continuously.
Background technology
At present explosive, the Drugs Checkout Gear of ion mobility spectrometry technology be a kind of fast, the on-site detecting device of sensitive, portable operation.This device has begun to be applied to military and safety check mechanism, can explosive detection, materials such as drugs, gas.
When ionic migration spectrometer detected prohibited items, except gas sampling (be commonly called as and hear flavor) mode, the most frequently used was the solid sampling mode.Promptly, explosive or drugs particulate are collected on the sampling carrier, again sampling carrier is inserted the pick-up unit injection port and detect identification earlier with sampling carrier (as sampling paper) wiping article surface.Contaminated for fear of sampling carrier, generally sampling carrier is installed on the special-purpose hand-hold wiping sampling thief and samples.As U.S. Pat 5859375A and PCT patent WO2007069088A3, described hand-hold sampling apparatus has sampling head that handle links to each other with handle and the setting that sample carrier is fixed on sampling head.Sample carrier is preferably pliable and tough flaky material, is installed in the collection position of device, staff not with the contacted condition of body surface under, realize also can carrying out sample collecting to the zone that is difficult to touch to the collection rapidly and efficiently of the sample in certain area.
Because the restriction of ionic migration spectrometer input mode requires the sampling carrier outward appearance necessary smooth, well-pressed, does not have crooked, non-wrinkle.The many sampling carriers that use curl or bending if having when storing at present, then are difficult for reverting to straightened condition in use, will influence sample detection, therefore present sampling carrier can only be made monolithic, once uses a slice, and sampling carrier takes place to curl or bending when avoiding storing.The present above-mentioned various hand-hold wiping sampling thiefs that use, the sampling carrier of use all is a monomer.Like this, each detection all will be taken out a slice from the sampling carrier storage facility, the test of installing then and sample, and this not only makes the sampling operation complexity, even more serious is that it very easily makes other untapped sampling carrier be polluted, and this storage to sampling carrier is very unfavorable.More aspect the selection of carrier material and the preparation technology in existing patented technology: as U.S. Pat 2006192098A1, to have described a kind of wiping sample paper of making by synthon that is used for trace detection, reduced the chaff interference that detection is caused by heating.Synthon comprise aromatic polyamides, as Nomex, Kevlar or the bond of the two.Have good chemical stability, when temperature is greater than or equal to 400 ℃, can not decompose, be applicable to trace analysis technology such as ionic migration spectrometer, mass spectrometer.Described analyte capture apparatus of U.S. Pat 6642513B1 or Wiping material are made of the glass fabric that the surface has the loose braiding of Teflon shallow layer; Also can be the non-braiding sense fabric of making by the high temperature polyamide fiber.But and reckon without carrier and use the problem that exists in the process of storing.
The utility model content
The deficiency that the utility model exists at above-mentioned existing sampling carrier; when being provided, a kind of storage do not curl; wrinkle not during use; can keep sampling carrier smooth well-pressed continuous sampling carrier and storage facility thereof after the sampling; use for the hand-hold wiping sampling thief; one-step installation is repeatedly used, and this sampling carrier and storage facility thereof can protect sampling carrier not to be subjected to the influence and the infringement of environmental contaminants.
For achieving the above object, the utility model adopts following technical scheme:
The utility model also provides a kind of device that sampling carrier can be provided continuously, described device comprises folding continuously sampling carrier, described sampling carrier is positioned at device, and described device is provided with lid and sampling carrier extraction opening, in described extraction opening sealing gasket is set.
According to the device that sampling carrier can be provided continuously of the present utility model, wherein, described folding continuously sampling carrier is the sheet elongate body, and the rectangular width of described sheet slightly is narrower than the width that uses this sampling carrier device portal.
According to the device that sampling carrier can be provided continuously of the present utility model, wherein, the rectangular sampling carrier of described sheet is made of several folding continuously layers along its length, its folding unit length and the suitable or several times of monolithic sampling carrier length of device of using this sampling carrier.
According to the device that sampling carrier can be provided continuously of the present utility model, wherein, be placed on the sampling carrier in the described container, the distance of 0.1-2.5cm is arranged between top layer after folding and the described internal tank end face.
According to the device that sampling carrier can be provided continuously of the present utility model, wherein, described container is metal or plastics rectangle box body, between described box body and lid, seal with welding or adhering method, be provided with duckbill sampling carrier extraction opening on one side of described box body, in described extraction opening, sealing gasket be housed.
Advantage of the present utility model and good effect are: can provide continuously to meet the cleaning sampling requirement, clean well-pressed sampling carrier can be for repeatedly sampling use behind the one-step installation sampling carrier.It is contaminated that the utility model is difficult for sampling carrier, helps the long term storage of sampling carrier; Be used with special sampler, can simplify the cleaning sampling operation steps, reduce staff's labour intensity, improve the Device Testing recognition efficiency.
