Profiling Analysis of the Degradation Products of Alkylphenol Polyethoxylates by LC-MS Using an Acclaim~(~R) Surfactant Column with Mass Spectrometric Detection

摘要

An LC/MS method was developed for quantitative analysis of APEO degradation products. Total chromatographic separation for APEOs and APs was achieved on a Surfactant column and MS detection was applied for selective and sensitive detection. Lower quantification limits for APEOs were estimated in the range of 0.05 to 2.4 ng/injection, and 5 ng/injection for APs. Linearity was achieved for each analyte within two orders of magnitude.
