Atomic Absorption Spectrophotometers

Atomic absorption (AA) has been known since the 19th century, but it was not until the 1950s, thanks to efforts by Alan Walsh at Australia’s CSIRO research center, that use of AA spectrometers became routine for metals analysis.

Flame Atomic Absorption (FLAA) Safety Precautions

by Other Author, Lab Manager

The oxidant/fuel combinations used in flame atomic absorption spectroscopy are commonly air/acetylene gas or nitrous-oxide/acetylene gas. Acetylene gas is highly ?ammable and can be potentially explosive.
