Characterizing Electrical Contacts Using the Chemreveal™ LIBS Desktop Elemental Analyzer
TSI Inc.
Connectors and tracks on printed circuit boards supply power and pass signals between electronic components soldered to the board. While primarily made of copper, alloying agents and overcoating are frequently used to improve the manufacturability and durability of traces and contact points. This note reports on analysis metals contacts on an intact circuit board using LIBS. In a single analysis, we obtain information on noble and transition metals as well as beryllium in copper.

EDXRF Application Note Electric Arc Furnace Slag #1343
Applied Rigaku Technologies
Rigaku EDXRF application note #1343 describes the analysis of iron, calcium, and silicon oxides in electric arc furnace slag (EAFS) for screening purposes and quality control. The results of this study indicate that the Rigaku NEX QC+ EDXRF analyzer can achieve excellent results in screening and monitoring the concentration of FeO, CaO, and SiO2 in electric arc furnace slag and similar matrices. EDXRF can also be used to measure other elements and oxides.
