Atomic Absorption Spectroscopy (AAS) is a widely used elemental analysis technique known for its affordability, simplicity of operation, and excellent sample throughput. It delivers accurate results for metals analysis across a broad concentration range and is often favored due to its low operating costs and minimal interferences compared to other methods. AAS is recognized in many international standard methods for metals analysis, making it a popular choice for both novice and experienced users.

2. What is Atomic absorption spectroscopy?
• Atomic absorption spectroscopy (AAS or AA spectroscopy) is
one of the earliest elemental analysis techniques to be
commercially developed. So, what is atomic absorption
spectroscopy? How does atomic absorption spectroscopy
work?

3. The electromagnetic spectrum. Atomic absorption spectroscopy uses light in the ultraviolet-visible
range

6. Sample introduction system

7. •Has the lowest capital cost, making it a more affordable
option
•Is a good technique for those new to spectroscopic
analysis, due to the simplicity of operation
•Can deliver excellent sample throughput for a single
element analysis
•Can measure samples over a wide concentration range,
from low ppm to percent levels, without the need to
dilute the sample
•Delivers accurate results
•Can easily be operated manually or can be automated
with an additional autosampler

8. Why use an atomic absorption spectrometer
• For the analysis of metals, the use of the atomic absorption
spectrometer (AA spectrometer) is a long established and well
accepted technique. It has remained a popular technique as it is easy
to use and provides both a high level of accuracy and sensitivity.
Importantly, AA spectrometry costs little to operate. There are also
few interferences in AA spectrometry compared with ICP-OES or ICP-
MS techniques, which makes analysis much simpler. The use of an AA
spectrometer is referenced as a preferred technique in many
international standard methods for metals analysis.
