Embodiment Construction

[0024] Firstly, the high-voltage discharge beam device (1) is used to generate high-voltage discharge beams to provide sufficient dissociation energy for atomic spectral analysis, and the adjustment and guidance of the discharge beam path is realized by means of the spectrum collection device (2) to avoid the loss of spectral energy transmission. If the dispersion speed is too fast, the sample vaporization device (3) is used for the preliminary treatment of the sample to realize the vaporization of the ground state atoms, combined with the sample injection device (4) to realize the introduction of the sample, and the beam filter device (5) is used to perform the spectral band analysis. Screening to avoid the influence of external interference bands, with the help of the spectral line separation device (6) for the adjustment and control of the characteristic analysis bands, to achieve selective filtering and shielding of the spectrum in a specific range according to different ana...

Description

technical field [0001] The invention relates to the field of spectrum analysis, in particular to a high-sensitivity atomic spectrum analyzer. Background technique [0002] The application of atomic spectroscopy analysis technology is mainly to transition to each excited state by absorbing the atoms or molecules in the ground state and low excited state of certain wavelengths of light with continuous distribution, forming dark lines or dark bands arranged according to wavelength. spectrum. The absorption spectrum is the white light emitted by a high-temperature light source, which is generated after passing through a relatively low-temperature vapor or gas, and the white light emitted by a high-temperature light source can generate a sodium absorption spectrum through a low-temperature sodium vapor. This spectral background is a bright continuous spectrum. A dark line appears at the position of the identification line of sodium. The position of the dark line in the absorpt...
