The status of thermospray sample introduction for analytical atomic spectrometry was last reviewed in 1992. In this review, we summarize developments in this field since that time, including investigations of aerosol generation processes, noise diagn

Axially viewed inductively coupled plasma–atomic emission spectrometry (ICP-AES) has encountered a resurgence in popularity over the past few years. It has been demonstrated that 5- to 10-fold improvements in limits of detection (LODs) can be obtai

A multi-tube Nafion ® membrane dryer used as a part of a desolvation system in conjunction with thermospray nebulization was optimized and characterized with inductively coupled plasma-atomic emission spectrometry (ICP-AES). Either argon or nitrogen

Matrix effects with fused-silica aperture thermospray (FSApT) sample introduction for ICP-AES are found to be higher than those for pneumatic sample introduction. The effects are comparable to those reported for sample introduction to ICP-AES using u
