英文摘要: This report describes the application of LC–MS/MS for the separation of dodecanol (C12OH) and homogenous fatty alcohols ethoxylated (AE) containing a dodecyl moiety and 1–9 ethoxy groups. These ethoxylates and free alcohol were derivatized for LC–MS/MS analysis with phenyl isocyanate (PIC). The derivatives of analytes with PIC were separated using a C18 column. Gradient elution with a mixture of ethyl acetate and acetonitrile (5 mM) was employed. The described determination method is characterized by low detection limits (range from 0.005 µg L−1 for: C12OH, C12EO2–7 to 1 µg L−1 for C12EO1) and quantification limits (range from 0.01 µg L−1 for: C12EO5–7 to 2 µg...
