IR in AA: Geology Applications 

Trophic level of an organism and health of an environment can be determined by comparing the nitrogen isotopes in trophic amino acids to that in source amino acids.

IR in AA: Analytes

​​Traditional methods use an Isotope-ratio mass spectrometer, which requires a large amount of analyte for  accurate measurements. 

​An orbitrap mass spectrometer has the resolution to view isotopes at much lower concentration, however there are sacrifices to accuracy.
​
This project aims to develop a method for stable isotope analysis on an orbitrap mass spectrometer. With the aim of prehistoric sample analysis.
