The toxicity of arsenic (As) depends on its chemical form, with inorganic arsenite (As(III)) and arsenate (As(V)) being the most toxic forms. These inorganic species are common in groundwater supplies, while organic arsenic species such as the non-toxic arsenobetaine (AB) may contribute most of the arsenic in seafood. To quickly and accurately assess arsenic toxicity, analysis of individual arsenic species is necessary, so Agilent has developed the Arsenic Speciation Kit for LC-ICP-MS
. The Kit links the Agilent LC to the Agilent ICP-MS systems. A validated analytical method is included, together with a speciation column for arsenic speciation in either drinking water or urine.
