애플리케이션

Ethyl 4-hydroxybenzoate (ethylparaben) was used to study the in-situ derivatisation solid-phase microextraction procedure for determining parabens, related chlorophenols, and triclosan in water.
Ethyl 4-hydroxybenzoate, a novel sorbent for solid-phase extraction, was used to study its retention property. It has high extraction efficiency towards the compounds tested owing to the electrostatic interaction, hydrophobic interaction and hydrogen bonding.

An in situ derivatization solid-phase microextraction method has been developed for the determination of parabens, triclosan and related chlorophenols in water. Acetylated derivatives are selectively determined using gas chromatography with tandem mass spectrometry. Parameters affecting both derivatization and SPME procedures
