Determining low levels of chromium in biological samples by ICP-MS using hydrogen as reaction gas

Chromium is a key ingredient in a number of metal alloys used for metal implants which, despite being coated with inert surface layer coatings, can break down over time as a result of biocorrosion. Leeching of metal ions from implants into surrounding bone, tissue, and body fluids can cause severe health problems.
