ICP specializes in analyzing metals and minerals. With this device, we can effectively and precisely determine the identity and quantity of any metal present in a sample, be it iron, magnesium, lead, mercury, or boron. The process to test for these metals is much more straightforward than it would be on the HPLC or LC‑MS/MS.
With an ICP‑OES, a sample flows into a plasma torch where it is incinerated into atomized particles. Electrons of the atomized sample go through different levels of energy, and by doing so, the atoms emit light. That light is analysed for meaningful information.
We use it to detect contamination by low-level trace metals including mercury, arsenic, lead, and cadmium. These contaminants permeate the Earth’s crust and can be especially present in foodstuff grown in the ground or any items originating from earth.
Essentially, the only remnants of an atomized sample will be any residual metals which we are then able to detect. This makes methods developed to test metals easier to run for on the ICP.
