Trace Elemental Analysis (TEA) Information
Trace elemental analysis
Chemical elements constitute all of the ordinary matter in the universe. Of the 118 elements that have been identified, 94 are found naturally on Earth, having either stable or unstable isotopes.
Because all matter differs in its elemental composition, it also differs in its chemical properties. Knowing the compositions or concentrations of elements in a given material can reveal several qualities about that material; e.g., geographic origin, product quality, process operation. Given its name, trace elemental analysis (TEA) inherently deals with the determination of small amounts of chemical elements; these small amounts often span a wide concentration range (e.g., 0.1% in rock composition, parts per trillion in semiconductor-grade chemicals).
Because it covers the analysis of elements, TEA is an integral discipline in understanding the natural world. As such, TEA can be applied to a wide variety of fields including environmental monitoring, pharmaceutical testing, food safety, geochemistry, petrochemistry, metallurgy, toxicology, forensics, and many other disciplines.
In this section, you will:
- Learn which TEA instruments and technologies are ideally suited to elemental sample analysis
- Find out when and why atomic absorption spectrometry (AAS), inductively coupled plasma optical emission spectroscopy (ICP-OES) are used to collect information about certain elements
- Understand how AAS, ICP-OES, and ICP-MS data are acquired and which techniques are regularly applied during the collection and processing of these data
- Find out which critical factors, including spectral interferences and physical interferences, must be considered during sample preparation for trace elemental analysis
