IAEA-NO-3 , Potassium Nitrate  

硝酸钾

Unit Size: 0.5g

IAEA-NO-3 is a dried salt (potassium nitrate, KNO3) and was prepared by A. Mariotti, Université Pierre et Marie Curie, Paris, France, between 1983 and 1985 [1, 2]. Its δ15N value is determined using data from an interlaboratory comparison [3].

USGS32 , Potassium Nitrate

硝酸钾

Unit Size: 0.5g

Report: IAEA-TECDOC-825

Date of Release:

International Chemical Safety Card (ICSC): ICSC_0184

USGS32 is a dried salt of potassium nitrate, KNO3 which was prepared in 1992 by J. K. B?hlke, U.S. Geological Survey [1] from Baker potassium nitrate (3190-01, lot #D40117 and 3190-05, lot #19162) and Cambridge Isotopes potassium nitrate (5% 15N, lot #F 2685). This salt material was prepared by dissolving and re-crystallizing a mixture of normal reagent salt and 15N enriched salts. Its δ15N value is determined using data from an interlaboratory comparison [2].

NSVEC , Nitrogen Gas-N₂

Inorganic , Gas

Unit Size: 7 ml

Report: IAEA-TECDOC-825

Date of Release:

NSVEC is a pure tank gas and was originally prepared by G. Junk and H. J. Svec, Iowa State University, USA [1]; C. Kendall, U.S. Geological Survey then split the sample into several hundred aliquots [2]. The δ15N value of this reference material is the result of the statistical evaluation of an interlaboratory comparison [3].

IAEA-N-1 , Ammonium Sulfate

Unit Size: 0.5g

IAEA-N-1 is a relatively coarse grained. salt of ammonium sulfate [(NH4)2 SO4] prepared by E. Salati, CENA (Centro de Energia Nuclear na Agricultura), Brazil, in the period of 1978 to 1983 [1, 2]. Its δ15N value is determined using data from several interlaboratory comparisons and assessments [2-5].

IAEA-N-2 , Ammonium Sulfate
