Description
Technical Field
The invention belongs to a fireproof and explosion-proof protection device for a sample small box to be tested in a laboratory, in particular to a fireproof and explosion-proof protection device for a small box for measuring inflammable and explosive products by a Raman spectrometer.
Background
In raman scattering, the scattered light frequency is reduced relative to the incident light frequency, referred to as stokes scattering, and thus in the opposite case, the frequency-increased scattering, referred to as anti-stokes scattering, is typically much stronger than anti-stokes scattering, and raman spectrometers typically measure mostly stokes scattering, also collectively referred to as raman scattering.
The frequency difference v between the scattered light and the incident light is called raman shift, which is independent of the frequency of the incident light and is related only to the structure of the scattering molecules themselves. Raman scattering is due to changes in the molecular polarizability (changes in the electron cloud). The raman shift is dependent on the change in the molecular vibrational energy level, the molecular vibrations characterized by different chemical bonds or groups, Δe reflecting the change in the given energy level, and thus the corresponding raman shift is also characterized. The Raman spectrum can be used as the basis of qualitative analysis of molecular structures.
Because raman spectroscopy can be used as qualitative analysis of molecular structures, the method is widely applied to the aspect of rapidly determining unknown substances, but if the unknown substances are inflammable and explosive substances, when high-energy light of a raman spectrometer irradiates the inflammable and explosive substances, the inflammable and explosive substances can be burnt as fire or explode immediately, and accidents occur.
