Facility:

OASIC currently has two isotope ratio mass spectrometers (MAT253 and Isoprime 100) and one laser absorption isotopic water analyzer (Los Gatos IWA-35d-EP with auto-injector and water vapor standard source). OASIC has capabilities for the isotopic analyses of hydrogen, carbon, nitrogen, oxygen, and sulfur.

  1. Thermo Scientific MAT253 IRMS with dual-inlet is coupled with Gas Bench and Thermal Conversion Elemental Analyzer (TCEA).

    facility

  2. Isoprime 100 IRMS is coupled with a Vario Microcube Elemental Analyzer.

  3. Los Gato Isotopic Water Analyzer (model IWA-45EP) - Off-axis ICOS.

    facility

  4. This compact fluorination line is equipped with a CO2 laser system (MIR-10, 25W) that floats above the sample chamber enabling the use of non-flexible tubing for lower blanks. Laser-heating (and fluorination) is controlled at the click of a mouse. This system can be used to extract oxygen from almost all non-carbonate oxygen bearing solids (e.g., silicates, oxides, phosphates, sulfates, etc.) for triple oxygen isotopic analysis.
