Service Description


Oxidation State-Specific Analysis of ArsenicĀ (Aqueous Solutions or Simple Biological Matrices)

Trivalent and pentavalent arsenic species in aqueous solutions or simple biological matrices (e.g., cell culture medium or urine) are analyzed directly (without extraction or chemical digestion) using hydride generation-cryotrapping-atomic absorption spectrometry (HG-CT-AAS). This method detects and quantifies 7 arsenic species, including arsenite, arsenate, methylarsenite, methylarsenate, dimethylarsenite, dimethylarsenate, and trimethylarsine oxide.

Oxidation State-Specific Speciation Analysis of Arsenic (Aqueous Solutions or Simple Biological Matrices) – Low Arsenic Content
Trivalent and pentavalent arsenic species in aqueous solutions or simple biological matrices (e.g., cell culture medium or urine) are analyzed directly (without extraction or chemical digestion) using HG-CT-inductively coupled with the plasma-mass spectrometer (ICP-MS). This method can detect and quantify very low levels of 7 arsenic species, including arsenite, arsenate, methylarsenite, methylarsenate, dimethylarsenite, dimethylarsenate, and trimethylarsine oxide.

Analysis of Total Arsenic or Selenium (Aqueous Solutions or Simple Biological Matrices)
Total arsenic or selenium in aqueous solutions or simple biological matrices (e.g., cell culture medium or urine) is analyzed directly (without extraction or chemical digestion) using HG-CT-AAS or graphite furnace (GF)-AAS, providing only information about the total amount of the element.

Analysis of Total Arsenic or Selenium (Complex Biological Matrices)
Total arsenic or selenium in complex biological matrices (e.g., sediments, cells or tissues) is analyzed after extraction or chemical digestion of samples, using HG-CT-AAS or graphite furnace (GF)-AAS and providing only information about the total amount of the element.

Speciation Analysis of Arsenic (Complex Biological Matrices)
Arsenic species in complex biological matrices (e.g., sediments, cells or tissues) are analyzed after extraction or chemical digestion of samples using HG-CT-AAS. This method detects and quantifies inorganic arsenic, methylarsenic, dimethylarsenic and trimethylarsenic without providing information on the oxidation state of arsenic in the above species.
