Anotace	Longitudinal distribution of Se free atoms in heated quartz tube hydride atomizers was studied under analytical conditions. The free atom decay rate is greatly enhanced at higher analyte concentrations, which is a source of calibration curvature. The presence of zones where once reacted atoms are reatomized at the tube ends was directly proven: the sensitivity is improved and calibration bending is attenuated. Recommendations concerning the quartz tube design and dimensions are given.
