“…Because the impurities in high purity ZrO 2 powder strongly influence its properties, it is of great importance to determine these elements at trace levels. Trace metal assay by direct current (D.C.) arc carrier distillation using a direct reading spectrometer (DRS) with photomultiplier tube (PMT) detectors for various matrices has already been reported by our laboratory (3)(4)(5).…”

A method for the direct determination of trace elements at concentrations as low as subppm and ppm levels in a ZrO 2 matrix has been developed by direct current (D.C.) arc carrier distillation, employing a charge coupled device (CCD)-based spectrometer using a 5% carrier combination of AgCl-SrF 2 (4:1). The CCD-based spectrometer was used to examine the analytical performance of a wider number of analytical lines and the determination of more analytes in comparison to earlier reports with a direct reading spectrometer (DRS) having a photomultiplier tube or photographic plate for detection.The analytical method developed in the present work has the potential to simultaneously determine 24 elements (Al,
