Application of Special Instrumental Analysis to the Analysis of Iron and Steel

The availability of high purity platinum-group metals is of prime importance to those investigating the structures and properties of these elements, many of which are profoundly affected by the nature, concentration and distribution of the impurities present Concentration of impurities and defects at the grain boundaries can strongly influence the mechanical characteristics of the metals By arc/electron beam melting and zone refining in high vacuum significant purification of all the platinum-group metals commercially available could be achieved [1]

High Purity Platinum-Group Metals

A procedure for the determination of nitrogen, oxygen, and hydrogen by spark-source mass spectrography is described. The reduction of instrument blank levels is an important consideration in this analysis. Factors which influence the blank level include vacuum, choice of sample etch, and baking of the source. A prespark of 100–300 nC is considered an integral part of the procedure, since it apparently removes the last traces of surface impurities. Blanks below 1 at. ppm have been observed. The procedure can also be applied for the determination of carbon.
