Embodiment 1
[0045] Such as figure 1 As shown, the ultraviolet analyzer of the present invention is composed of an ultraviolet light source 1, a narrow-band interference filter 7, a measuring gas cell 9, a reference side photodetector 10, and a measurement side photodetector 11. A rotatable light-cutting wheel 4 is provided on the side, and a gas filter 3 and a purple glass 5 are respectively provided at both ends of the light-cutting wheel 4. The gas filter 3 and the purple transparent glass 5 can be placed at the outlet of the ultraviolet light source 1 in turn through the rotation of the light cutting wheel 4 according to the need for light intake during actual measurement. The cutting motor 2 provides power for the cutting wheel 4.
[0046] The ultraviolet light source 1 uses a xenon flash lamp.
[0047] A partially reflecting lens 8 for increasing the reflected light is provided in the measuring gas chamber 9.
[0048] An adjustment lens 6 for adjusting the ultraviolet light to parallel l...
Embodiment 2
[0069] The other structure is the same as that of Embodiment 1, the difference is that the ultraviolet light source 1 uses a hollow cathode lamp, and the reference side photodetector 10 and the measurement side photodetector 11 both use photomultiplier tubes.
