Introduction of Atomic Absorption Spectrophotometer
Atomic absorption spectrometer is used to analyzes metal
elements according to the effect of atomic vapor in the ground
state of matter on characteristic radiation absorption, and it can
sensitively and reliably determine minor or trace elements.

Applications of Atomic Absorption Spectrophotometer
Atomic absorption spectroscopy is frequently utilized in
agriculture and the study of environmental sciences. Atomic
absorption spectroscopy, which analyzes the light emitted from a
sample rather than the light absorbed—are frequently used in
various fields of agricultural study. Typically, they’re used to
identify and analyze the presence of potentially harmful elements
in the environment.
Atomic absorption spectroscopy has been utilized in the study of
forensic sciences for many years. Common causes of metal poisoning,
such as mercury and lead, are easily detectable using this
technology and can be identified even in trace amounts.
