The Preparation of Metal Ingots for Use as Chemical and Spectrographic Standardsn.Table 1. Nominal Composition of B-1900.as long term chemical standards are prepared by normal foundary techniques. In both cases the levels of trace or contaminant elements obtained are difficult to predict, particularly when they are volatile at the melt temperature or do Rot alloy with the matrix.

Qualitative Analysis of Precipitates by Graphite Filter Methodse precipitates can be collected by a Millipore filter and easily analyzed qualitatively. When an x-ray fluorescence spectrometer is not available, or the suspected elements are not amenable to the technique, the methods described here are helpful.
