This paper presents a method for determination the trace contents of silver,  copper, iron, palladium, zinc and platinum in refined gold samples.  Simultaneous inductively coupled plasma atomic emission spectrometer with  radial torch position and cross flow nebulizer was used for determination. In  order to compare the different calibration strategies, two sets of  calibration standards were prepared. The first set was based on matrix  matched calibration standards and the second was prepared without the  addition of matrix material. Detection limits for matrix matching  calibrations were higher for some elements than those without matrix  matching. In addition, the internal standardization method was applied and  experiments indicated that indium was the best option as internal standard.  The obtained results for gold sample by matrix matching and matrix free  calibrations were compared with the obtained results by standard addition  method. The accuracy of the methods was tested performing recovery test.  Recoveries for spiked sample were in the range of 90-115 %. The accuracy of  the methods was also tested by analysis of certified reference material of  high pure goldAuGHP1. The best results were achieved by matrix free  calibration and standard addition method using indium as internal standard at  wavelength of 230 nm.
