The Uses of Sodium tetraethylborate
Sodium tetraethylborate is used as a derivatizing agent for the detection of organotin, lead and mercury compounds by using gas chromatography coupled with various sensitive and selective detection methods, such as atomic absorption spectrometry (AAS), atomic emission spectrometry (AES), pulsed-flame photometric detection (PFPD), and mass spectrometry (MS). It is also used as an alkylating agent.
