Description
Technical field the utility model is about spectroanalysis instrument.
Background technology is in existing spectral analysis technique, the qualitative identification of component and quantitative test, be confined to traditional light wave and can only play excitation generation spectrum valence electron and more stable unsaturated strong pi-electron, the compound of lone pair electrons that is in unstable energy level in the material molecule, therefore, the scope of mensuration material is restricted.
Summary of the invention task of the present utility model provides and a kind ofly almost can play excitation to all compounds and produce absorption spectrum, service band is in 200～1100nm scope, can measure material in the ultraviolet region, the absorption spectrum in visible region, infrared region, terahertz light district, and can in a sample, measure multiple component simultaneously and the wider spectrometer of mensuration material that needn't separate in advance.
The principle of this spectroanalysis instrument that the utility model provides is that the material component under the excitation of terahertz light energy level transition takes place, and produce component evident characteristic Terahertz absorption spectrum, the absorption peak of absorption spectrum and absorbance variation characteristic meet lambert-Beer law fully.By measuring the absorption curve and the absorption peak of material composition sample, carry out spectral analysis, thereby measured matter is carried out qualitative and quantitative.When the Terahertz light wave along the light path of setting during through measured matter, measured matter produces component evident characteristic Terahertz absorption spectrum, computing machine and storage were surveyed, change, imported to its absorption spectrum signal by terahertz detector after amplifying Terahertz standard absorption spectrum carries out data processing, and shows the output result by display.
This spectroanalysis instrument that the utility model provides by the Terahertz emitter and be installed on successively Terahertz emitter back light inlet slot, reflective mirror A, diaphotoscope B, quartz prism, reflective mirror C, diaphotoscope D, go out optical slits, cell, terahertz detector, amplifier, Computer Processing and as a result display form.
The effect of Terahertz emitter is to produce the terahertz emission ripple.THz wave is meant that frequency is 0.1-10 * 10 at 0.1-10THz
12Electromagnetic wave in the Hz scope, the effect of THz wave is to make the material component be subjected to exciting the generation energy level transition, and produces component evident characteristic Terahertz absorption spectrum.
Light inlet slot, the effect that goes out optical slits are the geometric configuratioies of control thz beam and regulate luminous flux.
The effect of reflective mirror A, reflective mirror C is to adjust the light path that thz beam does not depart from setting.
The effect of diaphotoscope B, diaphotoscope D is to focus on thz beam to become parallel beam.
The effect of quartz prism is that wavelength is regulated in beam split.
The effect of cell is to deposit to fill the measured matter cuvette.
The effect of terahertz detector is to survey the Terahertz absorption spectrum and it is changed into electronic signal.
The effect of amplifier is that the electronic signal that terahertz detector is surveyed and is converted to is amplified.
Computer Processing and the effect of display as a result are that the Terahertz standard absorption spectrum of signal after pair amplifier amplifies and Computer Storage is handled and shown and outputs test result.
The advantage of this spectroanalysis instrument that the utility model provides is that terahertz light almost can play excitation to all compounds and produces absorption spectrum, and can measure multiple component simultaneously in a sample and needn't separate in advance.
Appended drawings is the structural representation of this spectroanalysis instrument that provides of the utility model, wherein Terahertz emitter (1), light inlet slot (2), reflective mirror A (3), diaphotoscope B (4), quartz prism (5), reflective mirror C (6), diaphotoscope D (7), go out optical slits (8), cell (9), terahertz detector (10), amplifier (11), Computer Processing and display (12) as a result.The back of Terahertz emitter (1) is equipped with light inlet slot (2), reflective mirror A (3), diaphotoscope B (4), quartz prism (5), reflective mirror C (6), diaphotoscope D (7) successively, goes out optical slits (8), cell (9), terahertz detector (10), amplifier (11), Computer Processing and display (12) as a result.
Embodiment is introduced a course of work of this spectroanalysis instrument that the utility model provides below in conjunction with accompanying drawing.At first, pre-thermal instrument, be adjusted to dormant state, this look ware that will fill then through pretreated measured matter places in the cell (9), start Terahertz emitter (1) to producing stable Terahertz light wave, the Terahertz light wave after light inlet slot (2) is regulated luminous flux along light path to reflective mirror A (3), reflected light becomes directional light behind diaphotoscope B (4), after regulating wavelength, quartz prism (5) beam split reflexes on the diaphotoscope D (7) through reflective mirror C (6) again, becoming directional light shines on the cuvette that fills measured matter in the cell (9) through going out optical slits (8), its terahertz light excites measured matter, what the specific components of measured matter was subjected to THz wave excites the generation energy level transition, measured matter in the cuvette absorbs the absorption spectrum that produces self to terahertz light, spectral signal is surveyed through terahertz detector (10), conversion, after amplifier (11) amplify back input Computer Processing and as a result display (12) carry out data processing with Terahertz standard absorption spectrum, and show the output result by display.
