Features of Light Source

The light source thermally dissociates ozone that is formed from the ultraviolet radiation via the heat
generated by the xenon lamp itself. This allows the use of a fused-silica xenon lamp that produces
intense radiation even in the short wavelength region.
As a safety measure against failure or stoppage of the cooling fan, a thermal sensor works to extinguish
the xenon lamp in about 15 minutes if the fan stops during analysis at a room temperature of 27 °C, or in
about 20 minutes if the fan was stopped from the beginning, in order to prevent failure or damage of the
instrument.
