Analysis of nonyiphenol and nonyiphenol ethoxylates in environmental samples by mixed-mode high-performance liquid chromatography-electrospray mass spectrometry
Ferguson PL, Iden CR, Brownawell BJ. 2001. Analysis of nonyiphenol and nonyiphenol ethoxylates in environmental samples by mixed-mode high-performance liquid chromatography-electrospray mass spectrometry. Journal of Chromatography A. 938:79-91
A new method is described based on mixed-mode high-performance liquid chromatography with electrospray mass spectrometry detection for comprehensive quantitative analysis of nonyiphenol (NP) and nonyiphenol 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 [ CJNPEO analogs as isotope-dilution surrogate standards. Method detection limits for NP and individual NPEOs ranged from 1 to 55 pg injected on column. © 2001 Elsevier Science BY. All rights reserved.
