Particle sample introduction system for inductively coupled plasma–atomic emission spectrometry

Atomic Spectroscopy

“…Greib and Karanassios used the introduction of particulate matter into the ICP for programmable delivery of small amounts of diluted powdered samples to the ICP and reported stable operation of the plasma. It was possible to enter nanometer- and micrometer-sized materials and to determine refractory elements such as W, of which the signals were shown to increase by the addition of SF 6 to the ICP working gas.…”

“…Greib and Karanassios 215 have reported the development of a direct solid sample introduction system for programmable delivery of small amounts of diluted powdered samples into ICP-AES. The system was optimized for the analysis of nonhygroscopic powders with particle weights in the ng range.…”

“…The development and characterization of a new, relatively inexpensive, computercontrolled particle sample introduction system to an ICP-OES instrument has been described by Greib and Karanassios. 306 The device was designed to introduce non-hygroscopic particles of ng range weight (or samples that can be ground to form such particles) at a delivery rate that is controlled by a programme. The system was tested in three modes.…”
