Abstract
A hydrogen-flushed hydride generation utilizing a 1 % solution of NaBH4 as a reductant is wed with a non-heated quartz tube atomizer for selenium determination in feed and forage samples. A small amount of oxygen is added to the hydrogen to support combustion and atomization of the hydride. The sensitivity is 6 × 10−10 g. with linear analytical curves and good accuracy. The relative standard deviation of the method is 5–8 %.Keywords
