Instruments

Continuous Flow Isotope Mass Spectrometry (C, N, O & H)

Continuous Flow Isotope Mass Spectrometry (CF-IRMS) analysis is performed using a series of Thermo Delta V+ connected to a suite of peripheral Thermo instruments. These include a GC-Isolink gas chromatograph combustion system for compound specific isotope analysis (C & N), Flash EAs (C & N), Gasbench II carbonate analyzer (C & O), and TC/EA (O & H).

Laser Ablation Multi Collector Inductively Coupled Mass Spectrometer

This Laser Ablation Multi Collector Inductively Coupled Mass Spectrometer (MC-ICPMS) system was recently added to conduct isotopic analyses of heavier elements, such as strontium in fish otoliths, teeth and bones. These data can be used to address a wide range of research questions, including geolocation.

This LA-MC-ICPMS is the only one of its kind in Alaska.

Sample Weighing Room

Three microbalances in a dedicated weighing room at ASIF are available to all investigators to allow samples to be weighed. ASIF lab space is also available at both the light and heavy isotope labs to support investigators in preparing samples for analysis at ASIF.
