설명

일반 설명

Tetraoctylammonium bromide (TOAB) is an ionophore or recognition element mostly used in potentiometric sensors.

애플리케이션

TOAB has been used as recognition element in formulating potentiometric membrane to develop an electronic tongue system for monitoring nitrogen species level in water samples.[1] It may also be used as an ion pairing reagent for HPLC analysis during glucosinolate separation.[2]
