Description

Gate system for sample detection

Technical field

This application involves detection and analysis technical field is related to, in particular to a kind of gate system for sample detection System.

Background technique

In order to combat terrorist activities and drug smuggling, ion mobility spectrometry, gas-chromatography, gas-chromatography-are mainly used at present The technologies such as ion mobility spectrometry combination, gas chromatography-mass spectrography detect trace drugs, explosive.On such as airport, iron There is an urgent need to provide a kind of can rapidly and effectively be used for ticket, IC card or body under numerous occasions such as road, highway, meeting-place inlet and outlet Part card etc. carries out including device that the difficult higher boiling sample to volatilize such as trace drugs, explosive is acquired and analyzes.

The main clothes that checked object is wiped by test paper of the existing detection to trace drugs, explosive, baggages carry out Surface is sampled, after again through Thermal desorption to instrument analyze.And it is suitable for carrying out ticket, IC card or identity card etc. drugs, explosion The technology of the sampling analyses such as object is also rarely reported.Wherein Smiths disclose it is a kind of using air pump air-breathing and with absorption band adsorb adopt The method of sample；Hitachi reports a kind of using fladellum gas flow purging document surface and in conjunction with the progress of cyclone suction technology The method of sampling.It may be implemented to be sampled ticket, IC card, identity card etc. detection, but its sampling efficiency is low, the detection to instrument Sensitivity requirement is high, performance difficulty.

In a kind of existing sample trapping and its analyzing device, middle sample trap portion, which is divided into being equipped with, is wrapped in two Sample strip on spool is coated with sorptive material on sample strip.When sampling, sample is drawn to sample strip simultaneously by starting pump air-breathing It is adsorbed.After sampling again by the part for being adsorbed with sample be sent to thermal desorption area moment desorb after be sent to GC-IMS again It tests and analyzes.The technology can realize the problem of automatic, continuous sampling, be suitable for card, card sampling and detection.But its essence is still Belong to air suction type sampling, the method for sampling is to low with the firm drugs of higher boiling and adherency, explosive sample collecting efficiency.

In a kind of existing gate rays safety detection apparatus, using fladellum gas flow purging card, card surface and with cyclone air-breathing Sampling apparatus collects the sample fallen from card card and is finally re-fed into the gate rays safety detection apparatus that detection device is detected.It is this to adopt With strength fladellum gas flow purging card, card surface and the method for combining cyclone sampling, adopted compared to the sampling of direct air-breathing There is apparent improvement in sample effect, but uses fladellum air-flow to blow down sample from card card and caught by cyclone sampler It while collection, also has the sample that quite a few is blown down and is lost due to not trapped by cyclone sampling apparatus, and is drugs, quick-fried The higher boilings particles such as fried object are also not easy to be shot down by air-flow after by card card absorption, therefore this sampling technique is to drugs, explosive Sample effect be also difficult to further be promoted.
