Preparation of submicrogram nitrogen samples for isotope analysis by the gs 1 emission spectrometer

, : Preparation of submicrogram nitrogen samples for isotope analysis by the gs 1 emission spectrometer. International Journal of Applied Radiation & Isotopes 32(4): 215-218

A convenient method is described for the preparation of submicrogram N electrodeless discharge tubes without the addition of noble gas. The stable N isotope analysis was carried out by using the GS 1 emission spectrometer whose possibilities were tested. The preparative method described is particularly fitted for the analysis of biological samples [nitrate metabolism in corn] having a low 15N enrichment.
