Abstract

The initial approach after installation of the spectro-graphic laboratory is an evaluation of the analytical load. Generally speaking the elements sought are those which are important, in low concentrations, and which the chemical laboratory find difficult or time consuming. Hence, for steel laboratories copper and tin are given immediate attention. The technique as initiated in one week will not be precise but just adequate to place the laboratory upon a production basis. During the next ensuing short interval emphasis is placed upon obtaining a satisfactory A.C. Arc technique for Al, Cr, Mo, Ti, V, Ni, and Sn in residual concentrations. The successful completion of production control of residuals will serve to convince management of the ability of the spectrographers installation and the spectrographer, but more important, it will provide a grace period of several months in which the spectrographer can experiment with the more difficult A.C. Spark technique to arrive at a basic method compatible to the high concentration analysis he may be expected to handle. The manganese determination, of course, will be left to the last, as one by one each curve is cross-checked out against routine chemical analysis in the trial and correction run. The spectrographic assignment has now become one of supervision and equipment maintenance. It is at this point that the spectrographer may assume a new role, as a salesman of his equipment and his ability to be of service. To ascertain the new fields it will be necessary to become acquainted with the melters, furnace first helpers, blast furnace blowers, operating and claim metallurgists, chemists, research personnel, and forming mill foremen.
