The Determination of Selenium in Shampoo by AA
Rebecca Price, Thermo Fisher Scientific
Find out about an accurate and rapid method for the analysis of selenium in shampoo using flame atomic absorption spectrometry as detailed in the European Commission Cosmetics legislation, 5th Commission Directive 93/73/EEC.
 
The Analysis of Trace Elements in Honey by AA
Dr. Hazel R. Dickson, Thermo Fisher Scientific
Discover an ideal solution for the analysis of elements in honey. This note demonstrates how flame and furnace atomic absorption spectrometry can be used to measure major, minor, and toxic elements.
 
Lead in Natural Waters by Graphite Furnace AAS
Rebecca Price, Thermo Fisher Scientific
This method provides procedures for the determination of lead by graphite furnace atomic absorption spectrometry in natural waters following US Environmental Protection Agency methodology.
AA
Nitrogen Determination in Soils and Plants
Dr. Liliana Krotz and Dr. Guido Giazzi, Thermo Fisher Scientific
The resulting data obtained demonstrated excellent reproducibility and no memory effect was observed when changing the type of sample, indicating the complete detection of the nitrogen present in the sample. The nitrogen data obtained was inside the tolerance accepted by WEPAL International Round Robin Tests.
 
Biomass and Bio-fuels Characterization
Dr. Liliana Krotz and Dr. Guido Giazzi, Thermo Fisher Scientific
Biomass and bio-fuels characterization using CHNS determination with the Thermo Scientific FLASH 2000 CHNS/O Analyzer allows the quantitative recovery of the element from any matrix. Additionally there is not memory effect when changing the sample.
 
Performance through Food Reference Materials Analysis
Dr. Liliana Krotz and Dr. Guido Giazzi, Thermo Fisher Scientific
The Thermo Scientific FLASH 4000 Analyzer was able to analyze nitrogen in a wide range (from a low to high content) without a matrix effect. The resulting nitrogen data was inside the tolerance that is indicated in the reference material certificates for both Kjeldahl and the Combustion method.
AA
Trace Element Impurities in Tungsten Matrices
Andrew Clavering, Thermo Fisher Scientific
This application note describes the use of a matrix matching technique as used by prominent world-wide producers of pure metals and alloys to enable quantitative analyses of selected trace metal element contaminants in various metal enriched sample matrices.
 
Migratory Element Analysis in Toy Samples
Matthew Cassap, Thermo Fisher Scientific
An analysis of migratory elements from toys in hydrochloric acid using the Thermo Scientific iCAP 6200 ICP-OES was made simple by using the pre-loaded method template. This enabled excellent results to be achieved with a minimal requirement for method development.
 
Polymer Analysis for WEEE/RoHS Compliance
Andrew Clavering, Thermo Fisher Scientific
The analysis of polymer samples to verify compliance with WEEE-RoHS legislation is simple, rapid, and analyst-friendly with the Thermo Scientific iCAP 6200 ICP-OES. The preloaded method template enables even the most inexperienced users to dramatically reduce the normal method development time needed for typical WEEE-RoHS samples.
