Fundamental Information
contrAA 700 Issue 01/2014 7
1 Fundamental Information
1.1 Intended Use
The contrAA 700 is an atom absorption spectral photometer to allow sequential analysis of
metal and non-metal traces in liquid and dissolved samples. Running under PC control, the
contrAA 700 provides a high resolution continuum source atom absorption spectrometer tool
for flame, hydride and graphite tube technique. It is intended for determination of metal and
non-metal traces in liquid and dissolved samples.
Combined with an autosampler, the contrAA 700 can work as a multi-element automatic
setup for routine analytical jobs. It performs an initial calibration of the elements under
analysis by sequentially processing the related calibration standards at first and sequentially
processing the actual samples in a second step. Hence, after each sample measurement,
the results are available for all elements that were subject to analysis.
All operating selections such as spectrometer settings, burner height and fuel gas values
and temperature-versus-time programs for electro-thermic atomization are automatically
assigned in accordance with actual methodology parameters so they may differ from
element line to element line. The control software relies on the Windows operating system to
accomplish full operation control of the basic equipment unit and connected accessory items
plus related data acquisition and data evaluation processes. Including the analytical back-
ground is automatically determined and simultaneously available on the analysis line. The
control software includes standard values for methodological settings that relate to an
analysis line. Prefabricated line parameter settings are available for each measurable
element of the periodic table (also referred to as "cookbook”) to facilitate getting started in
analytics. They can be used as an initial base for editing one’s own multi-element
methodologies. The control software also provides comprehensive representation and
storage capabilities for signals and parameters measured, for GLP-compliant logging and
various quality control options, including a possibility to maintain and update quality control
cards.
