摘要：

A modified torch for use as a solid sampling system for laser ablation inductively coupled plasma-atomic emission spectrometry (ICP-AES) is described. The torch system could replace the conventional torch used for solution analysis. Preliminary results based on copper determination in standard steel samples in terms of precision (±10%) and accuracy (±20%) were considered acceptable though poorer than conventional solution ICP-AES. © 1991.
