title: First report on the detection and quantification of arsenobetaine in extracts of marine algae using HPLC-ES-MS/MS.
abstract: The detection of arsenobetaine in extracts of marine algae is reported here for the first time. The application of liquid chromatography coupled online with electrospray tandem mass spectrometry in the selected reaction monitoring mode provided improved performance for the detection of low amounts of arsenobetaine in the presence of high amounts of arsenosugars.
