Development of an Automated Trace-Matrix Separation Technique for the Determination of Trace Metals in Pure Titanium and TitaniumdioxideThe determination of metal traces in pure titanium with ICP-AES or ICP-MS requires an effective trace-matrix separation technique to eliminate interferences. After digestion in HF and HNO3 the traces can be separated from the matrix using a cation exchanger column. A computer controlled pumping system is used for the automatic control of the procedure of preconcentration, elution and determination. The method requires a minimum of chemical manipulation and reduces the risk of contamination by using only subboiled acids. Recovery rates of more than 90% and high precision are obtained for 16 analytes. For most of the elements detection limits in the range of 1 to 10 ng/g titanium can be achieved.
