  <dc:description>&lt;p&gt;Use of an argon-oxygen atmosphere eliminates the interference&amp;nbsp;of cyanogen bands with many sensitive analytical lines. The&amp;nbsp;jet-controlled atmosphere also improves the stability of the arc. These&amp;nbsp;procedural changes, coupled with computerized analysis of the spectra,&amp;nbsp;result in increased detectability, precision, and speed as compared to&amp;nbsp;the former visual semiquantitative technique.&lt;/p&gt;</dc:description>
