Abstract

The spectrographic analysis of alloys is frequently complicated in industrial laboratories where samples may be presented as large plates and blocks, chips from weld spots, turnings, or filings. The variety of sample sizes and shapes makes it difficult to establish standard sampling practice and excitation conditions.
