Alkyl sulfates mass spectrometry

Liquid chromatography-mass spectrometry is still difficult to use for routine analysis. However, the technique is essential for special projects, as was demonstrated for determination of the total alkyl and ethoxy distribution of alkyl sulfate and alkylether sulfate in wastewater (66). Because of the specificity of MS detection, a simple SPE technique could be used for concentration, and an equally simple one-step HPLC separation was adequate.
