Abstract
The utility model relates to a multi-channel atomic fluorescence optical fiber spectrometer, comprising radiation light sources and lens; the utility model is characterized in that 3 to 8 radiation light sources (3) and 3 to 8 lens corresponding to the radiation light sources are arranged inside the optical fiber spectrometer. The device adopts a plurality of lighting sources to radiate atomic vapor inside an atomizer in turn to make the atomizer generate different elements and fluorescence signals of different intensity which can be detected by a photoelectric detection device (4), converted into electrical signals and transmitted to an electrical switch (5); under control of demodulation signals, the electronic signals are separated into signals representing different elements and different intensity; finally, measurement results of a plurality of elements of the same sample are produced by a signal processing system.
Description
Technical field
The utility model relates to the atomic fluorescence spectrometer of using in a kind of analytical chemistry field, and particularly the hyperchannel atomic fluorescence spectrometer that the content of contained a plurality of elements in the analytic sample is measured simultaneously belongs to light, mechanical, electrical integrated analysis instrument.
Background technology
Atomic fluorescence spectrometry is by measuring the intensity of the atomic fluorescence that atom sent, coming the content of contained element in the test sample.At present, this technology and instrument have been widely used in fields such as environmental protection, health, food, medicine, metallurgy, geologic prospecting, in order to a plurality of elemental compositions contained in the analytic sample are measured.Because characteristics such as itself it is highly sensitive that this instrument has, and detection limit is low, and is simple in structure, analytical approach is comprehensive in addition, is very suitable for China's national situation.But, because of present homemade atomic fluorescence analysis instrument is single channel or channel structure, when a plurality of elements in the same sample are measured, because apparatus structure is limited, can only measure simultaneously 1-2 element at every turn, measure work when can't finish a plurality of element, must adopt repeatedly sequential determination just can finish.Required sample size is relatively large, minute is long, required cost height, particularly ask for something is carried out the industry of continuous detecting to a plurality of elements, as the mensuration of geological analysis to arsenic, antimony, bismuth, mercury, food hygiene and water analysis are measured to elements such as arsenic, antimony, selenium the time etc., can increase workload undoubtedly, bring scarcely just also for mensuration work.
Summary of the invention
The technical problems to be solved in the utility model is for overcoming the deficiency described in the background technology, and provides a kind of single element that both can carry out to measure, again the hyperchannel atomic fluorescence spectrometer that can measure simultaneously a plurality of tested elements in the sample.
To achieve these goals, the technical solution that the utility model proposes is: be provided with 3-8 radiating light source and 3-8 the lens corresponding with radiating light source in this spectrometer.
Further technological improvement of the present utility model is: single radiating light source and single lens constitute one group of illumination unit.Each focus of organizing illumination unit all concentrates on the same point of atomizer.
The utility model is owing to adopted the structure of hyperchannel illumination unit, outside decapacitation is measured the individual element in the sample, its biggest advantage is exactly to measure simultaneously a plurality of elements contained in the same sample, overcome the deficiency that can only adopt repeatedly sequential determination in the existing technology, can not only increase work efficiency, widen the usable range of instrument, shorten analysis time, reduce staff's labour intensity, can also save analysis cost.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Accompanying drawing shows one of them embodiment of the utility model, four groups of illumination units that constitute by radiating light source 3 and its corresponding lens 2 respectively (being four-way) have been adopted in the present embodiment, these four groups of illumination units are with fan-shaped distribution, and be fixed in the instrument by support, each focus of organizing illumination unit all concentrates on the same point of atomizer 1, and described radiating light source 3 is a hollow cathode lamp.
Each is organized illumination unit and both can floor plan also can three-dimensionally arrange in instrument, but the focus of all illumination units all should concentrate on the same point of atomizer 1.
Radiating light source 3 is under the control of light source control signal, the a certain moment in one-period has only a unique illuminator to be excited, and the atomic vapour that produced in the atomizer 1 this moment can send a characteristic fluorescence signal under the radiation of this feature light source.Owing in atomic vapour, have a plurality of elemental compositions, and each element is only to radiosensitive with own corresponding characteristic wavelength.The characteristic wavelength that each radiating light source 3 is sent in this instrument is all different, so, in a time cycle, sequentially light a plurality of radiating light sources, can produce the fluorescence signal of different elements, varying strength in atomizer 1, this sequence fluorescence signal is detected and is converted into electric signal by photoelectric detector (photomultiplier tube) 4, for the element fluorescence signal that is produced, as long as its wavelength all can be received by photoelectric detector 4 in photoelectric detector 4 fills the wavelength band of being permitted.From photoelectric detector 4 outputs are one group of pairing electric signal of fluorescence intensity, this group is mixed electric signal by electronic switch 5, under the control of restituted signal, be separated into the signal of the different elements of representative, varying strength, and level signal processing circuit is separately handled the separation that is effective again after being admitted to.Finally, the signal of being imported is gathered, changed and data processing, can obtain coexisting as the analysis result of a plurality of elements in the same sample at the same time by signal processing system.
The utility model has mentioned that the illumination unit that is made of radiating light source 3 and lens 2 is 3-8 group, i.e. 3-8 passage.Certainly, can in this scope, determine the number of illumination unit according to actual needs, to satisfy the needs of routine analysis.
