With both models, the monochromator is wavelength-stabilized by the use of an inte-
grated neon source. Wavelength reproducibility is achieved by the internal Ne-line cali-
bration of the monochromator when approaching a wavelength.
A low noise, UV-sensitive semiconductor detector (CCD line detector) is located at the
exit slit of the monochromator. This detector not only registers the intensity of the anal-
ysis line, but also its spectral neighborhood. In this way, a spectral range of up to 1 nm
in the vicinity of the analysis line is detected simultaneously and at a high resolution.

The autosampler ASPQ 3300 allows fully automated routine analysis. It can be equipped
with three sample racks and two racks each with 6 special samples, e.g., standards.
The following sample racks are available:

The purging vessel is installed at the autosampler. A peristaltic pump at the ASPQ 3300
delivers the wash liquid from the diluent bottle into the wash cup – this action cleans
the dipped cannula by washing it inside and out. Excess wash liquid is pumped into the
