We are looking for a  source of high-pressure nitrogen gas (100-200bar)
 enriched  in molecular 15N (15N2) to 0.5-1.0% levels. Total gas volume 

(14N2 + 15N2) of about 100-500 litres minimum volume at 1 bar.
  We know of pure (98%) 15N2 at 1 bar in litre
quantities,  but are looking for lower enrichment mixtures with 14N2.  

Ideas welcomed.
