Quadrupole ICP-MS

More than 70 elements can be detected simultaneously at trace levels by inductively coupled plasma-mass spectrometry (ICP-MS).

The Perkin Elmer Elan II DRC employs both standard and dynamic reaction cell (DRC) modes to analyze nearly all elements from Sc to U with high precision. DRC mode offers users the ability to analyze those elements with known mass interferences (e.g., As, Sb, Fe, etc.) with high precision to very low concentrations (< 1 ppb (ug/L). Reported detection limits on this instrument range from 0.1 ppt (0.1 ng/L) to 1 ppb (ug/L) for most elements.

High Performance Liquid Chromotography (HPLC)

The lab houses a Perkin Elmer S-200 HPLC with column oven and auto sampler that is coupled to the ICP-MS.  Elements with multiple valence states (As, Te, Bi, Pb, Sb and Se) can be separated in the LC column analyzed to levels as low as 1 -5 ppb (ug/L). We welcome new applications and method development projects to this emerging use of the coupled HPLC-ICP-MS system.

Laser Abation

Soild samples can be analyzed directly using coupled LA-ICPMS. This system can be used in conjunction with ICP-MS in either standard or DRC mode to analyze a host of compositions. Spot sized down to 25 um can be analyzed. Detection limits for many elements on the ICP-MS using the laser system are in the mid to high ug/L (ppb) range.
