Frequently Asked Questions (FAQs)

Q1. What is Nitrogen-15 (¹⁵N₂), and how is it different from ordinary nitrogen?
A: Nitrogen-15 (¹⁵N₂) is a stable isotope gas composed of two ¹⁵N atoms. Ordinary nitrogen (¹⁴N₂) is made of ¹⁴N atoms. Natural nitrogen contains about 0.36 atom % ¹⁵N. The chemical formula is ¹⁵N₂, and the CAS number is 29817-79-6. It is chemically similar to ordinary nitrogen but has a different atomic mass, making it useful as a tracer.

Q2. What are the main application fields?
A: It is widely used as a tracer in agricultural and environmental research (e.g., nitrogen cycle, fertilizer uptake), in biomedical studies (protein, amino acid, and nucleic acid metabolism), in NMR and mass spectrometry, and in the synthesis of ¹⁵N-labeled compounds.

Q3. What are its core physical properties?
A: It is a colorless, odorless gas at room temperature, with a boiling point of about −195.8 °C. It is about 7% denser than ordinary ¹⁴N₂ and slightly denser than air. It is chemically inert, non-flammable, and only slightly soluble in water.

Q4. How should it be stored correctly?
A: It should be stored in a tightly sealed high-pressure cylinder, kept in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. Store separately from flammable gases and strong oxidizers. Keep the valve closed when not in use to avoid leakage and contamination.

Q5. What basic safety precautions should be taken during handling?
A: Operators should wear safety goggles and gloves when handling cylinders. Avoid direct contact with the cold gas or liquid. Ensure adequate ventilation to prevent asphyxiation. It is non-toxic but can displace oxygen in confined spaces. In case of leakage, ventilate the area and close the valve if safe to do so.

Q6. Is Nitrogen-15 (¹⁵N₂) a greenhouse gas or a fluorinated gas?
A: No. It is a stable isotope of nitrogen, not a greenhouse gas, not a fluorinated gas, and not a perfluorocarbon. It is chemically identical to ordinary nitrogen and does not contribute to global warming.

Q7. Are there special requirements for transportation?
A: Yes. It is classified as a compressed gas (UN 1066, Class 2.2 — non-flammable, non-toxic gas) for land, sea, and air transport. It must be transported in sealed, approved cylinders, protected from rain, direct sunlight, and violent collision. Keep cylinders upright and secured, and separate from food and feed during transit.

Q8. What is the natural abundance of ¹⁵N, and what isotopic purities are available?
A: The natural abundance of ¹⁵N is about 0.36 atom %. Common enriched grades include 98 atom % ¹⁵N, 99 atom % ¹⁵N, and higher. Isotopic purity is typically verified by isotope ratio mass spectrometry (IRMS) or mass spectrometry. Custom purities may be available on request.

Q9. What are the main advantages of using ¹⁵N₂ as a tracer?
A: It is a stable, non-radioactive isotope that is safe to handle under normal conditions. It allows precise tracking of nitrogen transformation, uptake, and metabolism over long periods. It does not introduce radioactivity and is compatible with mass spectrometry, NMR, and other analytical techniques.

Q10. Do you offer custom isotopic mixtures or ¹⁵N-labeled compounds?
A: Yes. We can provide custom gas mixtures, various cylinder sizes and pressures, and ¹⁵N-labeled compounds or precursors. Please contact us at tao.hu@asiaisotope.com with your specifications for a quote.
