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].
