(2) Solution Samples, as shown in Fig.
The bulb in a halogen lamp is filled with inert gas and a small amount of a halogen.

The photoelectrons emitted from the photoelectric surface repeatedly cause secondary electron emission in sequentially arranged dynodes, ultimately producing a large output for a relatively small light intensity.

Although I coleman 5033 heater manual said in the previous section that the sample is exposed to monochromatic light, there are instruments in which white light is passed through the sample before being passed into the spectrometer.
