Abstract
ICP-AFS excited by hollow cathode lamp(HCL) with high current (15 A) a nd microsecond pulse (1.5 mu s) power supply has been studied. The det ection limit (2 sigma) for Ca obtained with an 850 W ICP was 0.07 ng/m L, which was 40 times better than that obtained with conventionally pu lsed (cp.) HCL excited at the same ICP power, and 30 times better than the best detection limit for cp. HCL, which was obtained with an 800 W ICP.
