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 1200 LC
to the Agilent 7700 ICP-MS
system, and is also compatible with the 1100 Series LC and 7500 Series ICP-MS instruments. A validated analytical method is included, together with a speciation column for arsenic speciation in either drinking water or urine.
