A <i>Bardócz BIG 210</i> ignited arc source was compared with a conventional ignited unidirectional arc and a <i>Multisource</i> for the analysis of lead alloys and the determination of boron in steel. The sources performed similarly except for the lead alloy analysis where the <i>Bardócz</i> source proved superior in repeatability and line-to-background ratio.
