Description
Technical field
The present invention relates to analytical chemistry Atomic absorption field, specifically relate to a kind of optical gate switchgear of line spectrum light path.
Background technology
Atomic absorption refers to the absorbing phenomenon that the characteristic spectral line that the atom pair in gaseous state is gone out by similar atomic radiation has.When on projecting radiation to atom vapor, if when the corresponding energy of radiation wavelength equals the energy of atom required for ground state transition to excited state, then the absorption of atom pair radiation can be caused, produces absorption spectrum.Ground state atom absorbs energy, and outermost electronics produces transition, transits to excited state from low-energy state.
Atomic absorption spectrum (Atomic Absorption Spectroscopy, AAS), i.e. atomic absorption spectrography (AAS), being the analytical approach coming based on quantitative tested constituent content to the absorption intensity of the corresponding atomic resonance radiant rays of ultraviolet light and visible-range based on the ground state atom outer-shell electron of gaseous state, is a kind ofly measure the method for specific gaseous atom to the absorption of optical radiation.This method occurs mid-term the 1950's and a kind of novel instrument analytical method grown up gradually afterwards, because of the feature such as sensitive, accurate, easy of Atomic Absorption Spectrometer, constant and the micro-trace elements analysis of the aspects such as metallurgy, geology, mining, oil, light industry, agricultural, medicine, health, food and environmental monitoring are now widely used in.
Atomic absorption spectrum as a kind of analytical approach of practicality from nineteen fifty-five.The famous paper " application of atomic absorption spectrum in chemical analysis " that the Wa Erxi (A.Walsh) of this year Australia has delivered him has established the basis of atomic absorption spectrography (AAS).The end of the fifties and the beginning of the sixties, Hilger, Varian Techtron and Perkin-Elmer company is successively proposed atomic absorption spectrum commercial apparatus, has developed the design philosophy of Wa Erxi.Arrived the mid-1960s, atomic absorption spectrum starts to enter the period developed rapidly.1976, FDAC (Hitachi) company was proposed Z-9000 type Atomic Absorption Spectrometer, adopted four-way system, can Simultaneously test 4 kinds of elements.
Along with the development of atomic absorption technique, promote continuous renewal and the development of Atomic absorption instrument, and other scientific and technological progress, for the continuous renewal of Atomic absorption instrument and development provide technology and material base.Using continuous light source and echelle grating, be combined vidicon, diode array multielement analysis detecting device, have devised micro-processor controlled atomic absorption spectrophotometer (AAS), opening new prospect for solving multielement simultaneous determination.Micro-processor controlled atomic absorption light spectra system simplifies apparatus structure, improves the automaticity of instrument, improves accuracy of measurement, makes the looks of atomic absorption spectrography (AAS) there occurs great change.
