Abstract

During the past few years, interest has grown in the role played in nutrition by the so-called trace elements. Present in minute quantities and either vital or toxic to plants or animals, these elements frequently elude all but the most sensitive analytical techniques; hence their name. With but a few exceptions, all of the trace elements are metallic and, as such are detectable by the emission spectrograph. For this reason, the spectrograph has turned out to be a valuable analytical tool in agriculture and biology.
