Determination of the more common light elements such as nitrogen and chlorine at trace levels is difficult because of their high abundance on sample surfaces, in materials used to build analysis instruments, and in the residual gas of the instrument vacuum. We present here a new approach to analysis of these elements: accelerator mass spectrometry (AMS)(More)

This is true for the Second Bond but may not be the situation when it comes to the First Bond, because during the Free Air Ball (FAB) formation, the Pd-Cu wire tip is melted and the Pd distribution on the FAB surface is(More)
