Powder D-C Arc



Keyword Definition

Spark and arc emission spectroscopy became practical for elemental analysis in the 1930s.  The sample must be a conducting solid.  The technique was common in geochemical laboratories in the 1950s and 1960s.

Skoog et al. (Principles of Instrumental Analysis, 6th edition, 2007; chapters 8 and 10) give more details.
