Be applied to binary channels atomic fluorescence spectrometer's total reflection and fall device of making an uproar

The utility model discloses a be applied to binary channels atomic fluorescence spectrometer's total reflection and fall device of making an uproar, including accurate universal joint, the special glass of tectorial membrane, an excitation light source, no. Two excitation light source, lens, no. Two lens, no. Three lens, atomizer, detector and atomizer rooms, the special glass of tectorial membrane fixes on accurate universal joint, and the special glass of accurate universal joint and tectorial membrane all sets up in the inside of atomizer room, is equipped with atomizer under the special glass of the inside of atomizer room, tectorial membrane. The utility model discloses simple structure, installation and convenient operation through the solid angle of adjusting accurate universal joint, seek best total reflection angle, can make the scattering and the total reflection of the stray light of reflection of excitation light source production the stray light that incides on the detector showing and reduce, have effectively overcome traditional atomic fluorescence spectrometer's optical system scattering and the serious problem of reflective jamming, and the background value of messenger's instrument effectively reduces, has promoted the SNR.
