Spectroscopy
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.
