Atomic fluorescence spectrometry is the spectral analysis technique that middle 1960s proposes and grow up, and is an important branch in the atomic spectroscopy, and it is the comprehensive and development of atomic absorption and atomic emission spectrum, is a kind of good trace analysis technology.
In the prior art; atomic fluorescence spectrometer is mainly used in and detects Hg; the ppt level of As, Se, Te, Bi, Sb, Sn or other elements detects; it is widely used in industries such as environmental protection, clinical medicine, agricultural, geology metallurgy, pharmaceutical industry, petrochemical industry; it not only can measure metallic element, and can be used for measuring nonmetalloid and organic compound indirectly.Atomic fluorescence spectrophotometric (AFS) is to utilize the wavelength of atomic fluorescence spectral line and the qualitative and quantitative analysis method that intensity is carried out material, its ultimate principle is that atomic vapour absorbs after the optical radiation of characteristic wavelength, atom is excited to high level, just launch the atomic fluorescence of certain wavelength when getting back to ground state then, analyze the content of the element of surveying again according to intensity of fluorescence.The basic structure of atomic fluorescence spectrometer comprises parts such as excitation source, atomizer, beam splitting system, detecting device, signal amplifier and data processor.
In the prior art, atomizer at the test request atomic fluorescence spectrometer of different elements has different ignition temperatures, and the most of control mode that adopts constant power output of the ignition furnace silk of the atomizer of existing atomic fluorescence spectrometer, the function underaction can't satisfy for the requirement that the atomizer temperature is adjustable.
So, designs and a kind ofly can regulate temperature in the atomizer stove, thereby the atomic fluorescence spectrometer of different ignition furnace silk power output has become the technical matters that needs to be resolved hurrily in the art at the test of different elements.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, a kind of ignition furnace silk power output regulating device that is used for atomic fluorescence spectrometer is provided, and it has solved technological deficiency and the design drawback that can not regulate the atomizer ignition temperature in the atomic fluorescence spectrometer.
The utility model is for satisfying above-mentioned purpose, by the following technical solutions: a kind of ignition furnace silk power output regulating device that is used for atomic fluorescence spectrometer, comprise atomizer and be arranged at ignition furnace silk on the described atomizer, described ignition furnace silk is connected with power supply, be connected with control module between described ignition furnace silk and the described power supply, described control module is controlled the dutycycle of described electric power output voltage to regulate the output power of described ignition furnace silk.
Further, described control system control module is made up of the computer control unit, circuit board control module, the electric power driving module that connect successively, and described electric power driving module is arranged between described ignition furnace silk and the described power supply.
Further, described computer control unit is a single-chip microcomputer.

Other purposes of the present utility model and advantage can be further understood from the disclosed technical characterictic of the utility model.State with other purposes, feature and advantage and can become apparent on the utility model for allowing, embodiment cited below particularly also cooperates appended graphicly, is described in detail below.
Description of drawings
Fig. 1 is the structural representation of the ignition furnace silk power output regulating device that is used for atomic fluorescence spectrometer of one of the utility model embodiment;
Label declaration among Fig. 1: atomizer 11, ignition furnace silk 12, power supply 13, computer control unit 14, circuit board control module 15, electric power driving module 16.
Specific embodiments:
Please refer to shown in Figure 1, a kind of ignition furnace silk power output regulating device that is used for atomic fluorescence spectrometer of the present utility model, comprise atomizer 11 and be arranged at ignition furnace silk 12 on the atomizer, ignition furnace silk 12 is connected with power supply 13, be connected with control module in addition between ignition furnace silk 12 and the power supply 13, control module is made up of the computer control unit 14, circuit board control module 15, the electric power driving module 16 that connect successively, electric power driving module 16 is arranged between ignition furnace silk 12 and the power supply 13, in the present embodiment, computer control unit 14 is a single-chip microcomputer.
The principle of work of whole device is: after the user chooses the igniting power that needs, move by computer control unit 14 announcing circuit plate control modules 15 executable operations by software setting, circuit board control module 15 specified control interfaces output pulse width modulation (PWM) signal on request immediately, it is the square-wave signal in the accompanying drawing, the driving power driver module is carried out, concrete driving process is: when electric power driving module 16 is received the low level control signal, electric power driving module 16 internal switch circuit disconnect, circuit between priming supply 13 and the ignition furnace silk 12 is disconnected, and it is 0 that ignition furnace silk 12 is in output power; When electric power driving module 16 was received high-level control signal, electric power driving module 16 internal switch closings of circuit made priming supply 13 directly act on ignition furnace silk 12, realized that stove silk 12 output powers are 100%.
Therefore, the high-low level time by regulating control signal at interval just can control action in the voltage duty cycle of ignition furnace silk 12, thereby realize the adjusting that ignition furnace silk 12 power are exported.The high level dutycycle of control signal (PWM) is big more, and the average voltage that is loaded on the ignition furnace silk 12 is big more, and the two is linear.By regulating the dutycycle of control signal (PWM) signal, just can realize the purpose of point of adjustment stove silk 12 output powers, thereby realize different ignition furnace silk demanded power outputs.
