Spectrometer
Introduction
The core of the optical system comprises a dual Echelle monochromator with a dual,
backside-illuminated, cooled, CCD detector. The system is specifically designed for
ICP-OES. Computer controlled transfer optics direct the radiation from the plasma
into the monochromator. The optics housing is sealed and continuously purged with
high purity nitrogen.
Signals at the required analytical wavelengths are measured using a scanning CCD
(charged coupled device) based technology, with simultaneous measurement of the
background emission and a neon spectrum for active wavelength correction.
Transfer Optics
The computer controlled transfer optics are used to select either radial or axial
viewing of the plasma and to direct the radiation from the plasma onto the entrance
slit of the monochromator. The exact viewing position, horizontal and vertical
position, can be selected in the software.
An automatic shutter closes between measurement cycles to reduce the exposure of
the optics to excess UV radiation.
