Intensity Test
Intensity Test
The intensity test measures the intensity of the UV-lamp over the full wavelength
range (190 - 640 nm). Four spectral ranges are used to evaluate the intensity
spectrum. The test is used to determine the performance of the lamp and optics
(see also “Cell Test” on page 132). When the test is started, the 1-nm slit is
moved into the light path automatically (G7117B only). On the G7117A/G7117C,
the 4 nm fixed slit is used. To eliminate effects due to absorbing solvents, the
test should be done with water in the Max-Light Cartridge Cell or with the
Max-Light Cartridge Test Cell. The shape of the intensity spectrum is primarily
dependent on the lamp, grating, and diode array characteristics. Therefore,
intensity spectra will differ slightly between instruments.

Online-Help of user interface).
