IMPURITY TESTING VIA INORGANIC CHEMISTRY
For analysis of heavy metals and minerals, we have two Agilent 7700 ICP-MS systems (Inductively-coupled plasma mass spectrometry). The ICP source converts the atoms of the elements in the sample to ions by high temperature. These ions are then separated by their mass and detected by the mass spectrometer. This process is highly sensitive, allowing for analysis down to concentrations in the parts-per trillion for some ions. The technology is reproducible, even when analyzing trace metals. In addition, interference removal and matrix tolerance is a critical part of our approach, which allows us to analyze different sample types. As a result, our customers have an accurate measurement of results, including heavy metal contamination and mineral composition.
