Low Nitrogen Rock Preparation and Analysis

Eva Stüeken developed this method and then published it. IsoLab does not yet have an SOP in the same style as other SOPs. However, the supplemental documentation within Eva's publication is very clear and serves as a great starting point. The publication as well as two diagrams that may be useful are listed below.

• Stüeken EE, Buick R, Schauer AJ (2015). Nitrogen isotope evidence for alkaline lakes on late Archean continents. Earth and Planetary Science Letters 411, 1-10. doi: 10.1016/j.epsl.2014.11.037.
  • Grab Appendix A: Supplemental Material which has an MS word document describing all the methods.

I have read and understood the present SOP and, before starting work outlined in the present SOP, I will complete all required training.
