A new method is described based on mixed-mode high-performance liquid chromatography with electrospray mass spectrometry detection for comprehensive quantitative analysis of nonylphenol (NP) and nonylphenol ethoxylates (NPEOs) in wastewater and sediment. Efficient separation, reduced band broadening, and high sensitivity were achieved by employing a methanol-water gradient on a mixed-solvent gel filtration column designed for MS interfacing. Quantitative accuracy and precision of the method were improved by the use of custom-synthesized [C-13(6)]NPEO analogs as isotope-dilution surrogate standards. Method detection limits for NP and individual NPEOs ranged from B.V. All rights reserved.
