Page Content

The Ó£ÌÒÊÓƵ Center for Trace Analysis (CETA) coordinates analytical services provided by the Ó£ÌÒÊÓƵ Division of Marine Science. Most specifically, this means trace element analysis utilizing the division's high resolution inductively coupled plasma-mass spectrometer (HR-ICP-MS). CETA's ultimate mission is to provide state-of-the-art expertise, training, analytical services, and research in trace chemical analysis.


Our Offerings

  • Elemental Analysis of Waters and Solids by High Resolution Inductively Coupled Plasma Mass Spectrometry
  • Other Services Available Include Nutrient and Particulate Carbon-Nitrogen Analyses as well as Sample Collection and Preparation.
  • Proven Experience in Trace Element Analysis.
  • Application to Environmental, Health, Forensic, Semiconductor, & Life Sciences.
  • Unparalleled Limits of Detection in Elemental Analysis
  • *NEW: Analysis of O18/O16 and D/H ratios in water


Our Services

By high resolution ICP-MS:

  • Elemental analysis
  • Isotope ratio analysis
  • Isotope dilution analysis

Other services:

  • Solids dissolution
  • Sample collection
  • Nutrient & chlorophyll analysis
  • Particulate carbon-nitrogen analysis
  • Ion chromatography
  • Training in aquatic chemistry & ICP-MS

Our current facilities do not permit quantification of organic compounds or determination of light stable isotope ratios such as C13/C12 or N15/N14.


Unparalleled Limits of Detection

(ppt is parts per 1012, ppq is parts per 1015).

Unparalleled Limits of Detection

LOW SAMPLE REQUIREMENTS: Use of a micro-flow nebulizer means we can do most analyses with < 1 mL of sample! Also available: a desolvating micro-nebulizer.


Applications of (HR-ICP-MS)

  • Environmental & Earth Science: Elemental analysis of waters, rocks, soils; isotope ratio determinations to better than ±0.1% for Pb, Sr, and Li isotopes.
  • Semiconductor Industry: Determination of reagent purity.
  • Forensics: Elemental fingerprinting of crime scenes and stolen or recovered items.
  • Health & Biological Sciences: Elemental analysis for drug purity and the presence of trace elements in tissues and fluids.
  • Nuclear Industry: Tracing and confinement of reactor wastes.


Costs

For HR-ICP-MS analysis:

  • Academic/government labs: $170/hour
  • Commercial/private: $205/hour
  • Water isotopes: $21/sample (10-sample minimum)


For budgeting purposes: we can analyze "typical" dissolved samples at a rate of approx. 50/day. We will also charge for sample/standards preparation and data processing.
