Determination of ionic compounds in Antarctic samples using ion-chromatography coupled to mass spectrometry
The aim of the present work was to develop an analytical method for the quantification of anionic and cationic compounds (Cl-, Br-, I-, NO3-, MSA, SO42-, PO43-, C2-oxalic acid, C2-glycolic acid, C2-acetic acid, C3-malonic acid, cis-usC4-maleic, trans-usC4-fumaric, C4-succinic acid, αC7-benzoic acid,...
