Air-sampling of three tertiary amines (triethylamine, dimethylisopropylamine, dimethylethylamine)

After a brief review of the main publications dealing with air-sampling and analysis of aliphatic amines, the authors propose and investigate two sampling methods (bubbling through a sulfuric acid solution, trapping on sulfuric acid-treated silica-gel) for three tertiary aliphatic amines commonly encountered in foundries.
