the volume of nh4no3 solution, oxygen flow-rate, flame stoichiometry, sample holder type and the sample mass range were evaluated. calibration step was feasible using adsorbed reference solution in pelletized high purity graphite avoiding the use of certified reference material (crm). sample masses ...
Zn-citrate was separated on weak anion-exchange convective interaction media (CIM) diethylaminoethyl (DEAE) monolithic chromatographic column using \\{NH4NO3\\} as an eluent. Separated Zn species were determined by flame atomic absorption spectrometry (FAAS) or inductively coupled plasma mass ...
