Atomic Absorption Spectrscopy (AA) is an important spectrophotometric technique for analyzing samples for a particular element. The spectrophotometer uses an acetylene flame as the sample cell and ...

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...

The novel sensor demonstrated effectiveness in the spectrophotometric analysis of liquid samples. It enabled continuous mapping of absorption spectra along its entire fiber length, facilitating ...
