Nebulizer selection is a critical but often overlooked aspect of inductively coupled plasma–optical emission spectroscopy (ICP-OES) analyses. There are many different nebulizers available for ICP-OES, and choosing the optimal one can be confusing and difficult. To achieve peak performance from your ICP, it is essential to choose the proper nebulizer based on your sample types in addition to any necessary accessories to maintain long-term performance. In this study, we compare the performance of Glass Expansion’s most popular concentric nebulizer designs for ICP-OES applications as well as a parallel-path nebulizer from another vendor, providing a complete selection guide based on performance and design.

The patented D-Torch design uses high precision engineering to provide the benefits of lower running costs, chemical inertness and configurable injector geometry.

Glass Expansion designed and patented the D-Torch, a revolutionary, demountable torch. The D-Torch uses high-precision engineering to provide the benefits of a demountable torch, such as lower running costs, chemical inertness, and configurable injector geometry, without compromising usability, performance, or durability. In this report, we discuss the effects of harsh matrices on torches, as well as the features, benefits, and improvements in analysis achieved with the D-Torch.

The elegant design of the Elegra results in a very compact accessory (Figure 1), making it easy to fit every ICP model without overcrowding the sample compartment. The Elegra utilizes highly efficient membrane technology to add moisture to the argon as it flows through the inert metal-free construction. The device runs at atmospheric pressure and does not require heating or electric power. The Elegra is also configured with a bypass switch so that the operator can turn humidification on and off without connecting or disconnecting any tubing. For easy installation on any ICP instrument and nebulizer, each Elegra Kit is packaged with customized gas connectors.

An ICP optical spectrometer suffers from many challenges when faced with high salt samples. This work describes the selection of the best components and accessories for this application.

This article offers some suggestions for routine maintenance and offers guidance to troubleshoot common problems encountered in the ICP-MS sample introduction area.

The analysis of naphtha was accomplished without dilution. A reduced nebulizer gas flow and a spray chamber temperature of -25C yielded the highest sensitivity and best precision and detection limits.

Strategic modifications were made to the sample introduction system of an ICP optical spectrometer in order to improve precision, reduce drift and carryover, lower detection limits and speed analysis.
