Product of Arkema Inc.

Application

Triethylamine has been used during grafting of 5,6-epoxyhexyltriethoxysilane on a silicon device.

General description

Triethylamine (TEA, Et3N) is an aliphatic amine. Its addition to matrix-assisted laser desorption/ionization (MALDI) matrices faffords transparent liquid matrices with enhanced ability for spatial resolution during MALDI mass spectrometric (MS) imaging. A head-space gas chromatography (GC) procedure for the determination of triethylamine in active pharmaceutical ingredients has been reported. The viscosity coefficient of triethylamine vapor over a range of density and temperature has been measured.
