Arsenic's biggest analytical trap isn't a mineral acid or a mystery precipitate — it's the starting material itself. Depending on the form arsenic came in, you may be measuring As(III) or As(V), and the two don't give you the same intensity. This one-page reference covers what you need to know before you run an As analysis: solution chemistry, oxidation state effects, and the interferences to watch for on both ICP-OES and ICP-MS.
Everything you need to work smarter, from sample prep to final analysis
