Establishment of rapid, sensitive, and quantitative liquid chromatography‐electrospray ionization‐tandem mass spectrometry method coupled with liquid–liquid extraction for measurement of urinary bisphenol A, 4‐ <i>t</i> ‐octylphenol, and 4‐nonylphenol

Abstract

The established method was also applied effectively for the determination of BPA, 4-t-OP, and 4-NP levels in 15 human urine samples. This method was specifically developed for easy and precise analysis of BPA, 4-t-OP, and 4-NP in human urine. The method developed has been shown to be accurate, precise, and sensitive.
