Description	Stanovení chromu v prostředí obsahující chloridy použitím Zeeman ET AAS (cs) Chromium was determined in chloride matrix by the electrothermal atomic absorption spectrometry (ET AAS) using transversally heated graphite atomizer (THGA) and Zeeman effect background correction. The optimisation of temperature program was performed with chromium solution contained 0,5 % (w/v) NaCl and 10 % (v/v) HNO3, which is typical matrix of digested instant soups and supplements. The effect of concentration and type of modifier (ascorbic acid, NH4NO3, Li, NH4H2PO4, Pd, Rh and V) on the behaviour of chromium was tested. For each modifier used, a magnetic field strength was also optimised and strong dependence was observed for Pd and especially Rh modifier. A high efficiency of thermal stabilization and excellent sensitivity with Pd and Rh modifier were obtained even thought relatively low concentration of modifiers were used (125 mg.l-1 Pd and 62.5 mg.l-1 of Rh). The characteristic mass was evaluated for NH4NO3 1,7 pg, V 1,7 pg, Pd 1,0 pg and even Rh 0,9 pg.
