General description

三乙胺（TEA）是一种脂肪族叔胺。

Application

三乙胺已用于结合n-羟基琥珀酰亚胺（NHS）基团与氨基处理的针尖表面。它也被用作酰化反应的碱性催化剂。

Biochem/physiol Actions

三乙胺是一种流动相改性剂，用于酸性、碱性和中性分子的反相高效液相色谱（RP-HPLC）分离。它通过抑制药物和其他化合物的尾迹和稳定性来提高氨基酸和氨基酸酰胺的分辨率。
三乙胺（TEA）可以作为碱和增溶剂促进甲苯与 TEA 的反应。

Atomic force microscopy is a technique capable to study biological recognition processes at the single-molecule level. In this work we operate the AFM in a force-scan based mode, the jumping mode, where simultaneous topographic and tip-sample adhesion maps are acquired.
