ANALYSIS OF NATIONAL-INSTITUTE-OF-STANDARDS-AND-TECHNOLOGY ORE AND UNITED-STATES-GEOLOGICAL-SURVEY SAMPLES BY INDUCTIVELY-COUPLED PLASMA SPECTROSCOPY LASER-INDUCED BREAKDOWN SPECTROSCOPY

Al, Ca, Cu, Fe, K, Mg, Mn, Si, and Ti were determined in a series of N ational Institute of Standards and Technology aluminum and manganese o re and U.S. Geological Survey manganese nodules using both inductively coupled plasma (ICP) spectroscopy and laser-induced breakdown spectro scopy. The two methods of analysis will be compared and contrasted as to sample preparation, difficulty of analysis, cost of instrumentation , and values obtained for the analysis of standard reference materials .
