Inductively Coupled Plasma-Mass Spectrometry : A Rapid Technique for Multi-Elements Determination at the Ultra-Trace Level

 

20150707_161353a

Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at concentrations as low as one part per trillion. ICP-MS is undoubtedly the fastest growing trace element technique available today. It allows determination of elements with atomic mass ranges 7 to 250. It is able to detect the elements upto part per trillion levels and this ability to carry out rapid multi-elements  determination at the ultra-trace level  have made it very popular in diverse range of applications areas  including environment, geochemical, semiconductor, metallurgical, nuclear, chemical, climatic and biotechnology. In recent years, industrial and biological monitoring has presented major need for metal analysis by ICP-MS. Other uses is in the medical and forensic field, specifically, toxicology and heavy metal poisoning.

Arsenic and its Effects on Human Health

Arsenic has different toxicological properties dependent upon both its oxidation state for inorganic compounds as well as the different toxicity levels exhibited for organic arsenic compounds. As a consequence of the many different uses of arsenic and arsenicals, there is wide spectrum of situation in which human may be exposed to the element. The clinical picture of chronic poisoning with arsenic varies widely.

Arsenic Speciation Analysis using High Performance Liquid Chromatography-Inductively Coupled Plasma-Mass Spectrometry

Speciation is the analytical activity of identifying and/or measuring in a sample the quantity of one or more individual chemical species.  Arsenic has different toxicological properties dependent upon both its oxidation state for inorganic compounds as well as the different toxicity levels exhibited for organic arsenic compounds. HPLC is the technique of choice in modern speciation analyses due to their resolution and the ease with which they are coupled to ICP-MS, allowing for on-line separation and detection.
