High-Precision Analysis of Battery Materials with a Truly Simultaneous ICP-OES

December 05, 2019

This application note shows the ability of PerkinElmer's Avio® 500 ICP-OES to achieve RSDs < 0.1% for matrix elements in simulated battery materials, thanks to its ability to perform true simultaneous measurements.

Impurities in Aluminum Following London Metal Exchange Guidelines with the Avio 200 ICP-OES

December 05, 2019

This work illustrates the ability of PerkinElmer’s Avio® 200 hybrid scanning ICP-OES to accurately and reliably measure impurities in aluminum at levels specified in the London Metal Exchange.

Meeting the USP and Guidelines with ICP-OES

September 01, 2018

With its advantages-compared to ICP-MS-in matrix tolerance, robustness, simplicity, and cost, ICP-OES may be the technique of choice for the analysis of medications with low daily doses. For such analyses, the use of high-pressure, high-temperature microwave digestion in sealed containers simplifies sample preparation and prevents the loss of volatile elements.

Optimized ICP-MS Analysis of Elemental Impurities in Semiconductor-Grade Hydrochloric Acid

September 01, 2017

A closer look at the use of a cell-based ICP-MS approach that utilizes ion–molecule chemistry to reduce many of the traditional spectral interferences seen in the analysis of high-purity hydrochloric acid used in manufacturing integrated circuits and semiconductor devices

Micronutrient Analysis from Soil to Food: Determination by ICP-OES

November 01, 2016

The nutritional value of food depends on many components, including vitamins and minerals. While both of these occur naturally, they are also commonly added during processing to increase the nutritional content. Naturally occurring nutrients enter plants (and ultimately animals who consume plants) from the soils in which they grow, so it is equally important to monitor the nutrient content of both soil and final food products. Since the number of elemental nutrients is limited and they are present at relatively high concentrations, ICP-OES is an ideal technique for their measurement in soil and food. This work will focus on the elemental nutrient analysis of soils and two categories of food products: milk and fruit juice, whose nutritional content is particularly important as they are commonly consumed by young children.
