Polymethacrylate sorbent for the solid-phase extraction of amines

The use of solid-phase extraction with polymethacrylate for the gas chromatographic determination of dimethylamine, trimethylamine, ethylamine, triethylamine, propylamine, dipropylamine and tripropylamine in aqueous solutions was studied (detection limits of 0.7–1.0 μg dm⁻³).
