This article discusses the safety practices of using organic solvents in flame atomic absorption spectroscopy, reminding analysts to maintain safety awareness when working with flammable solvents.
This document addresses the potential dangers of combining open flames with flammable solvents in atomic absorption spectroscopy. It emphasizes that while these methods are common, human error can lead to accidents, and strict safety protocols are essential for laboratory personnel.
The guide provides specific instructions on solvent selection, such as choosing those with high flash points and specific gravity above 0.75. It details operational procedures for aspirating solvents, managing waste, and cleaning equipment, including warnings against using chlorinated hydrocarbons and leaving flames unattended.
