Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
The Inductively Coupled Plasma Mass Spectrometry (ICP-MS) laboratory is equipped
with a Thermo Fisher Element-XR magnetic sector ICP-MS which allows measurement
of isotopes from 6Li through 238U (mass up to 254UO)
at three resolution modes; low (m/Δm = 300), medium (m/Δm = 4,000) and
high (m/Δm = 10,000). The extended linear dynamic range of 1012
counts per second allows for improved quantification of major and trace elements in
the same analysis sequence with proper detector cross-calibration. The instrumentation
allows for bulk sample analysis via sample digestion and solution aspiration (SA)
ICP-MS, and in situ analysis via the
LA-ICP-MS Laboratory.
Sample dissolution for SA-ICP-MS is done in the ARES
Isotope Chemistry Laboratory.
An Elemental Scientific SC-E2 Autosampler is used to automatically control the analysis
sequence for SA-ICP-MS. An Apex Q desolvating nebulizer is available for enhancing
sensitivity of SA-ICP-MS analyses for samples of limited mass (for example, clasts
in breccias, chondrules), or with low elemental concentrations (for example, dunites,
orthopyroxenites). The laboratory has an extensive collection of certified international
reference rock powders for quantification via solution aspiration analyses of geological
samples.

Center for Isotope Cosmochemistry and Geochronology (CICG)
The Center for Isotope Cosmochemistry and Geochronology (CICG) led by Justin Simon
is based in the Astromaterials Research and Exploration Directorate at NASA Johnson
Space Center. Our team measures a wide variety of elements and their isotopes to
understand the origin of our Solar System, the processes that transformed nebular
dust and gas into the building blocks of planets, and planet formation (accretion
& differentiation).
