| Abstract: | Conditional tests was done on Hitachi AAS of model Z - 5000 with Orthogonal experiment method while measuresing gold, which in a lamp electric current, an acetylene flow, an air pressure, slit width, burner height, measurement time. That determine a lamp electric current to be 5mA, an acetylene flow to be 1.8L/min, an air pressure to be 140kPa,slit width to be 1.3nm, burner height to be 5mm, measurement time to be 3s. Have to out the burner height is a main factor that affect instrument of measurese. |
