Commercial 15N2 Gas Contamination and Nitrogen Fixation Measurements

Data associated with the PLOS ONE manuscript 'The contamination of commercial 15N2 gas stocks with 15N-labeled nitrate and ammonium and consequences for nitrogen fixation measurements'. The dataset reports on the presence of 15N-labeled nitrate, nitrite, ammonium, and nitrous oxide contaminants in commercial 15N2 gas and the resulting enrichment of particulate nitrogen from biological assimilation. Author Richard Dabundo published this work under an Open Access license.

Use Cases

• Calibrating nitrogen fixation measurements based on reported 15N-labeled contaminant levels.
• Assessing bias in biological nitrogen assimilation studies based on the enrichment data.
• Evaluating the quality of commercial 15N2 gas stocks for environmental research.
• Modeling the impact of isotopic contaminants on experimental results in biogeochemistry.

Strengths

• Data is directly associated with a peer-reviewed manuscript published in PLOS ONE.
• Focuses on a specific, documented issue of contamination in a widely used scientific reagent (15N2 gas).
• Published under an Open Access license, facilitating reuse and verification.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file format are unknown, which may limit suitability assessment.
