Metal speciation

Metal speciation

The toxicity and bioavailability of an element is to a large degree decided by the form in which it is present. For this reason, element speciation analysis is relevant in cases where elevated levels of a certain element are obtained. Arsenic (As), for example, may be present in the non-toxic form arsenobetaine which is dominant in plants and marine species. Arsenite on the contrary is classified as carcinogenic.
ALS offers the below element speciation analysis in clinical samples:

Total arsenic (As)
Arsenite (III)
Arsenate (V)
monomethylarsonate MMA (V)
Dimethylarseinate DMA(V)

Instrumental technique: IC-HG-ICPMS

Total mercury (Hg)
Methylmercury (MeHg)

Instrumental technique: GC-ICPMS

Total selenium (Se)
Selenite (SeIV)
Selenate (SeVI)

Instrumental technique: LC-HG-ICPMS
