Analysis of Gold by Flame Atomic Absorption
Rebecca Price, Thermo Fisher Scientific
This application note presents two methods for analyzing gold. The first uses an aqua regia sample digestion method, while the second follows a cyanide leach protocol. A Thermo Scientific iCE 3000 Series Atomic Absorption Spectrometer was used and proved to be the ideal technique and instrument to meet the analytical requirements. |

High Precision ICP-OES Analysis for Precious Metals
Andrew Clavering, Thermo Fisher Scientific
High precision analysis of valuable samples such as gold, silver, platinum, and palladium is important as small errors can have large cost implications. Typically ICP-OES does not meet the precision requirements for this analysis on a routine basis. The Thermo Scientific iTEVA Precision Software now enables ICP-OES instrumentation to meet the requirements. |

The Analysis of Steels and Alloys by ICP-OES
Andrew Clavering, Thermo Fisher Scientific
The preparation of steel samples for ICP-OES analysis often involves a complex and time consuming acid digestion of the sample. Laser ablation systems coupled to ICP-OES removes the need for the digestion step, as analysis of the solid takes place directly. This not only reduces the time taken for the analysis, but also reduces contamination and loss of analytes. |

Elemental Impurities in Liquid Pharmaceuticals
Matthew Cassap, Thermo Fisher Scientific
The analysis of pharmaceutical products for trace elements is traditionally carried out by insensitive wet chemistry methods. The United States Pharmacopeia is proposing new methods to replace the wet chemistry methods with instrumentation. Find out how ICP-OES can meet the requirements of the proposed methods when analysis liquid pharmaceutical products. |

Chromium Speciation in Cement Extracts
Shona McSheehy, Fabienne Seby, and Martin Nash, Thermo Fisher Scientific
This application note describes the use of a Thermo Scientific HPLC ICP-MS analytical solution to enable the determination of chromium species in cement extracts and airborne workplace particulates. Chromium species were separated on-line prior to ICP-MS detection using a cation exchange stationary phase in conjunction with a 100% aqueous acidic mobile phase. |
