Component
Description
1
Xenon flash lamp
Light source for the UV to near-infrared wavelength
range
2
Lamp optics
Focuses the light beam emitted from the xenon flash
lamp so that the beam passes through the excitation
monochromator
3
Excitation
monochromator
Lets only light with the selected excitation wavelength
pass
4
Flow cell
The eluent with the analyte travels through the flow
cell. The excitation light passes the flow cell to the
reference sensor, the fluorescence light exits the flow
cell at an angle of 90° to the excitation light.
5
Reference sensor
Measures the excitation light that passes the flow cell
and is used to compensate lamp fluctuations
6
Emission optics
Focuses the light beam emitted from the flow cell so
that the beam passes through the emission
monochromator
7
Filter wheel
Carries the optical filters, which are used to cut off light
below the cut-off wavelength of the selected filter
8
Emission
monochromator
Lets only light with the selected emission wavelength
pass
9
Photomultiplier
tube (PMT)
Converts light into a measurable current
10
Second PMT
Measures light in the near-infrared region (up to
900 nm)
