Description	Fractions of Cu and Zn species in legume samples (common white bean, pea, chick pea and lentil seeds and defatted soybean flour) were analyzed by on-line hyphenation of size exclusion chromatography and inductively coupled plasma-mass spectrometry. Samples were extracted by 0.02 mol/L Tris-HCl buffer solution, pH = 7.5. The extraction efficiency lay in the region 60 - 90 % and 60 - 80 % for Cu and Zn respectively. Quantification of elements in the individual chromatographic fractions was carried out by isotope dilution (ID) and external calibration (EC) techniques. For ID analysis the chromatographic effluent was mixed with the flow of 65Cu and 68Zn isotope enriched solution and the isotope ratio values 63Cu/65Cu and (64Zn+66Zn)/68Zn were measured. In the case of EC technique calibration solutions of elements were injected to the flow of mobile phase by the second injector. Prior entering detector the effluent was mixed with the flow of internal standard solution (In, 50 g/L). Both methods have simil Fractions of Cu and Zn species in legume samples (common white bean, pea, chick pea and lentil seeds and defatted soybean flour) were analyzed by on-line hyphenation of size exclusion chromatography and inductively coupled plasma-mass spectrometry.
