Abstract

Laser sampling inductively coupled plasma mass spectrometry (LS-ICP-MS) is a increasingly popular technique for the direct determination of trace elements in solid materials. In this technique, a high-power pulsed laser is used to vaporize a portion of a solid specimen. The sample vapor is then swept into an ICP discharge, which ionizes the vapor before it is subsequently sampled by a mass spectrometer.
