While separation of inorganic arsenic species can be easily achieved with a simple isocratic method, the presence of various arsenic compounds in real samples makes it impossible for accurate determination of toxic inorganic arsenic. A common gradient flow technique used by many testing laboratories faces two issues: long analysis time and potential overlap of high concentration levels of AsB on inorganic Arsenic species.

In this work, the isocratic method would be a better choice for seafood samples which usually contain high AsB, while toxic As(V) and As(III) were eluted much earlier. This allows toxic species to be detected accurately without worrying about high AsB tailing into the next species.
