Atomic absorption spectroscopy is a technique for determining the
concentration of a particular metal element in a sample.
Atomic absorption units have four basic parts: interchangeable
lamps that emit light with element-specific wavelengths, a sample
aspirator, a flame or furnace apparatus for volatilizing the sample,
and a photon detector. In order to analyze for any given element,
a lamp is chosen that produces a wavelength of light that is absorbed
by that element. Sample solutions are aspirated into the flame.
If any ions of the given element are present in the flame, they
will absorb light produced by the lamp before it reaches the detector.
The amount of light absorbed depends on the amount of the element
present in the sample. Absorbance values for unknown samples are
compared to calibration curves prepared by running known samples.
Atomic Absorption Spectrophotometer
The newly developed, high throughput dynamic beam
manager system achieves measurements with the world's highest
level of sensitivity (Direct determination - Flame: Pb, 0.1ppm;
Furnace: Pb, 0.3ppb)
A next generation double beam system which drastically
reduces the noise of a double beam optical system through
the adoption of a high throughput dynamic beam manager system
and a high speed operation digital filter.
The newly developed "WizAArd"
software - a match for this electronic records era - is much more
easier to understand and use, as well as being more secure
• In order to strengthen the security of electronic records,
the ability to manage using login ID names and passwords, management
of usage authority restriction according to user level, electronic
signatures, and audit trail functions have been equipped as standard.
QA/QC functionality as required by the U.S.
Environmental Protection Agency (EPA) has been improved even further.
Hardware validation software is also standard equipment.
Switch smoothly between Flame and
All that is involved in switching from flame to furnace is to
remove the burner head and put in place the furnace section. These
steps require no tools, and can be done easily and speedily.
Furthermore, the single autosampler can be used for both flame
and furnace, which negates the need to prepare the autosampler
for each analysis method.
Adoption of Automatic Burner Head
Height Control Mechanism
In addition to the automated control of the flame gas flow rate
conditions, the burner head height can be automatically controlled
as well. The optimal parameters for each element/ sample can be
set automatically to enable continuous measurement.
