The analytical potential of ICP-AES (ICP) and 3He+-activation for the determination of boron was examined. The paper compares ICP-levels of B, obtained from aqueous solutions containing digested plant material, with minimum detectable limits attained in solid matrices that were subjected to prompt gamma-ray analysis using 2 MeV 3He+ ions. The analytically useful gamma-rays originated mainly from (3He,p) and (3He, α) reactions on 11B and Coulomb excitation of 10B. The numerical capabilities of the two techniques for such measurements are discussed, and detailed methodologies and possible difficulties are presented.
