Atomic Absorption Spectrophotometer is for determining the concentration of a particular metal(element) in a
sample. Atomic Absorption Spectrophotometer can be used to analyze the concentration of over 62 different metals.
The technique makes use of absorption spectrometry to assess the concentration of an analyte in a sample. It relies
therefore heavily on Beer-Lambert law. In short,
the electrons of the atoms in the atomizer can be
promoted to higher Orbitical's for an instant by
absorbing a set quantity of energy (i.e. light of a
given wavelength). This amount of energy (or
wavelength) is specific to a particular electron
change in a particular element, and in general, each wavelength
corresponds to only one element. This gives the technique its elemental
selectivity. As the quantity of energy (the power) put into the flame is known, and the quantity
remaining at the other side (at the detector) can be measured, it is possible, from Beer-Lambert law, to calculate how
many of these transitions took place, and thus get a signal that is proportional to the concentration of the element being
measured.
TECHNIQUES
In order to analyze a sample for its atomic constituents, it has to be atomized. The sample should then be illuminated by
light. The light transmitted is finally measured by a detector. In order to reduce the effect of emission from the
atomizer(e.g. the black body radiation) or the environment, a spectrometer is normally used between the atomizer and

the detector. The technique typically makes use of a flame to atomize the sample,[3] but other atomizers such as a
graphite furnace[4] or plasmas, primarily inductively coupled plasmas, are also used.[5]When a flame is used it is
laterally long (usually 10 cm) and not deep. The height of the flame above the burner head can be controlled by
adjusting the flow of the fuel mixture. A beam of light passes through this flame at its longest axis (the lateral axis) and
hits a detector.
ANALYSIS OF LIQUIDS
A liquid sample is normally turned into an atomic gas in three steps:
Ÿ Desolvation - the liquid solvent is evaporated, and the dry sample remains
Ÿ Vaporization - the solid sample vaporises to a gas
Ÿ Atomization - the compounds making up the sample
FEATURES
Ÿ Built-in computer data processing and LCD:adopting highly integrated micro digital circuit, which is stable and
reliable with the functions of integral holding, peak height and area, auto zero adjusting, deuterium lamp and
background, multi-linear and nonlinear curves fitting, various parameters and working curves displayed in screen
and report printing, etc. It is equipped with interface for externally linking PC.
Ÿ Good basic line stability:Double-beam system of optimized design can automatically compensate the light source
drift and wavelength drift caused by the variation of temperature (with the function of the eliminating the affection of
wavelength drift on the base line stability) and electronic circuit drift so as to reach a good basic line stability. The
cathode lamp needs not be pre-heated for long time and sample can be analyzed immediately.

It is the preferable instrument chosen by users to conduct analysis of multiple kinds of elements and fast analysis of
samples.
Ÿ High precision of measurement:Gas path system is equipped with precision pressure stabilizing and current
stabilizing devices to reach stable flame and low noise. Specially designed fine light beam passes through the
flame to ensure a high precision analytical test and low characteristic concentration.
Ÿ Optical path of high energy: A total reflection system is adopted to eliminate color difference in full range. By means
of chemical conversion, a round light spot of the light source becomes a long light spot, which enters into the slit.
Therefore the light flux of double beam is enhanced.
Ÿ Long-life and anti-corrosive atomization system: The burner is made of new type titanium alloys, anti-corrosive and
fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling.
Ÿ Multi-functional analysis mode: for methods of flame absorption, flame emission, graphite furnace atomic
absorption (AS-3020 automatic sample feeder can be installed) and hydride generation.
Ÿ Safe and reliable gas path system: Special devices of quick gas conversion and safety protection can be used to
analyze air-acetylene flame as well as nitrous oxide-acetylene flame and extend the analytic elements to reach
more than 60.
Ÿ Complete set of accessories: to be supplied with the instrument and ready for use after they are purchased.
