Determination of nanogram amounts of nickel by flameless atomic-absorption spectroscopy.
A simple flameless atomizer, made from a heated graphite resistor, was investigated for the determination of nickel in various salts. The parameters characterizing its behaviour were optimized, to yield an absolute detection limit of 0.1 ng of nickel.
