Abstract
The utility model provides a hot blow sampling device used for noncontact sampling of an ion migration spectrometer. One end of the air pressure gun chamber of the device is provided with an acicular hollow head; and the other end of the air pressure gun chamber is connected with a sample attached piece fixer through an inside enclosing sampling tube thereof. A sieve is fixed inside the sampling tube. A heating device and a fan are arranged inside the air pressure gun chamber. The heating device is a resistance wire. A hollow piston rod is arranged in a chamber inside the sample attached piece fixer, which is coaxial with one end of the sampling tube, namely, the end connected with the sample attached piece fixer. A sample cell is arranged at the joint between the sampling tube and the hollow piston rod. A sample attached piece is inserted in the sample cell. A spring is enclosed on the hollow piston rod. The end of the rod is connected with a suction pump through a hose. The hot blow sampling device samples solid or liquid without contacting the solid or liquid, thus eliminating the inconvenience resulting from direct sampling as well as reducing collected granules such as dust and so on, and further reducing the pollution to instruments. The acicular gun head is designed to be inserted in such confined space as packages and so on for sampling.
Description
Technical field
The utility model relates to the Sampling techniques of ionic migration spectrometer, and the sampling apparatus of solid and fluid sample is gathered in especially a kind of noncontact.
Background technology
Ion mobility spectrometry (Ion Mobility Spectrometry, IMS) technology is a kind of separation detection technology that occurs the external seventies in last century, the eighties this technology being applied to on-the site analysis detects, its ultimate principle is: in atmosphere or migration gas tested gaseous sample ionization is formed ion, ion drifts about in extra electric field then.Because the mobility difference of different samples, thereby the heterogeneity in the sample obtains in migration tube separately, and then just can differentiate the composition of sample according to the transit time that measures.
At present, the sample mode that ionic migration spectrometer is commonly used is: solid sample adopts with the wiping of sample attachment flaps and obtains; Fluid sample extracts with liquid-transfering gun, syringe etc. and obtains, and perhaps dips in the sample attachment flaps and gets acquisition.But these sample modes are difficult for carrying out in some occasion, such as the article that do not allow directly contact are sampled, or when enclosure space inside such as parcel, container are sampled, seem powerless.And cleaning sampling can be gathered particles such as dust in the lump, can pollute instrument like this, and then influence detects.
Summary of the invention
The utility model provides the hot blow of a kind of noncontact sampling to sweep sampler, can sample to enclosure space inside such as parcel, containers, and can avoid particle such as dust to be brought in the detector with sample.
The utility model provides a kind of hot blow that is used for ionic migration spectrometer noncontact sampling to sweep sampler, this device comprises following assembly: filter screen 2, sampling pipe 3, air pressure gun chamber 4, sample attachment flaps fixator 7, hollow piston rod 8, sample cell 10, sample attachment flaps 11, flexible pipe 12, aspiration pump 13, heating arrangement and fan, and concrete annexation is:
Described air pressure gun chamber 4 one ends are equipped with pin type hollow head 1, so that can insert enclosure space samples, the other end links to each other with sample attachment flaps fixator 7 by cover sampling pipeline 3 in it, filter screen 2 is fixed in the sampling pipe 3, is used for particle such as blocks dust and enters sampling pipe and be enriched on the sample attachment flaps 11; The inside cavity in air pressure gun chamber 4 is equipped with heating arrangement and fan 6, and heating arrangement is a resistance wire 5, is used to add the air in the heat gun chamber, and whether may command it heat and reach gas flow temperature, and described fan is used for the air in the air pressure gun chamber is blown out, its switch of may command; Hollow piston rod 8 is installed in the sample attachment flaps fixator 7 inner cavitys, and is promptly coaxial with the end that sample attachment flaps fixator 7 links to each other with an end of sampling pipe 3; Described sample attachment flaps fixator 7 is used for fixing the sample attachment flaps; Sampling pipe 3 is equipped with sample cell 10 with hollow piston rod 8 joints; Be with spring on the bar of hollow piston rod 8, under the cooperation of spring, hollow piston rod 8 can be in fixator move left and right, be used to compress sample attachment flaps 11 in fixator do not pass sample attachment flaps 11 so that sample gas has with leaking; Rod end links to each other with aspiration pump 13 by flexible pipe 12.
The hot blow that the utility model provides is used for ionic migration spectrometer noncontact sampling is swept sampler, and heating arrangement is a resistance wire, 5～15 millimeters of pin type hollow head 1 internal diameters, and sample cell 10 is wide to be 1～30 millimeter.
The utility model course of work is as follows: pulling hollow piston rod 8, sample attachment flaps 11 is inserted sample cell 10, unclamp hollow piston rod then, the sample attachment flaps promptly is pressed in the fixator, open fan 6, aspiration pump 13 this moment, and resistive heater 5 energisings.Pin type hollow head 1 sample that aims at the mark is purged a period of time, the hot gas gasification that target sample is blown or purged and break away from the object that adheres in sample.Because in the sampling pipe 3 is air-breathing, promptly form negative pressure at place, pin type hollow head stopple coupon road junction, sample vaporized or that break away from can be inhaled into sampling pipe smoothly, again because of the temperature of sample cell place temperature far below pin type hollow head place, and then the sample of sample gas or disengaging then is enriched on the sample attachment flaps, can finish sampling.
The utility model has the advantages that:
1, to solid, liquid noncontact sampling, the inconvenience that can avoid direct sample to bring, it is collected to reduce particle such as dust again, and then reduces instrument and pollute;
2, aciculiform rifle head design can be inserted in the enclosure spaces such as parcel and be sampled;
3, the utility model, simple in structure, easy to process, be easy to mass production;
