Inductively Coupled Plasma Mass Spectrometry
Agilent™ 7700x equipped with a hyperbolic quadrapole mass spectrometer (ICP-MS)
The 7700x has excellent sensitivity with detection limits for most naturally occurring elements in the parts per billion (ppb) and parts per trillion (ppt) ranges, the 7700x also has the capability to run High Matrix Introduction (HMI) samples such as undiluted seawater, which is a first for ICP-MS instruments. We use an ASX 500 autosampler and Agilent Integrated Sample Introduction System Discrete Sampling, which is fully automated allowing us for higher throughput and accuracy by automating our calibration and sample dilutions.
ICP-MS works by atomizing samples using argon plasma, detecting isotopic elemental concentrations using a hyperbolic quadrupole mass spectrometer, and then comparing sample concentrations to appropriate elemental standards.
While most naturally occuring elements are detectable at low levels Hydrogen, Carbon, Nitrogen, Oxygen, Fluorine, Chlorine, and noble gases are not detectable; please refer to Available Services for details on the elements that interest you.
