The elemental analysis of materials is often a critical parameter in product quality and safety. For example, the correct elemental composition of raw material feed to a cement kiln is critical for smooth operation and maximum efficiency.
Equally as important, the presence of potentially harmful elements such as sulfur, sodium, potassium and mercury, must be carefully monitored as these can interfere with the process or damage the environment.
The technique best suited to accomplish elemental analysis depends on the material, its location, and industry-specific criteria.
Elemental Analysis Techniques
There are many elemental analysis techniques, which serve in understanding the elemental composition of substances. It provides valuable insights into the chemical makeup of materials, helping researchers and industries make informed decisions. Whether it's analyzing the purity of pharmaceuticals, identifying contaminants in food, or characterizing geological samples.
X-ray Fluorescence (XRF)
X-ray fluorescence (XRF) is a non-destructive technique that relies on the emission of characteristic X-rays when a sample is exposed to X-ray radiation.
It is widely used for elemental analysis in diverse applications, including alloy identification, mineral exploration, and quality control in manufacturing.
Pulsed Fast Thermal Neutron Activation Analysis (PFTNA)
Pulsed fast thermal neutron activation (PFTNA) is a specialized technique that utilizes pulsed fast thermal neutrons to activate materials.
It offers unique advantages in the analysis of trace elements and isotopes in various samples, including geological, environmental, and nuclear materials.
Inductively Coupled Plasma (ICP)
ICP is a high-temperature plasma source that excites atoms and ions in a sample, allowing for precise quantification of elements.
It is a versatile technique used in environmental analysis, geochemistry, and the determination of trace elements in various matrices.
Atomic Absorption Spectroscopy (AAS)
AAS measures the absorption of light by free atoms in a sample. It is particularly useful for quantifying trace metals in biological and environmental samples, making it indispensable in analytical chemistry.
Neutron Activation Analysis (NAA)
NAA involves bombarding samples with neutrons to induce nuclear reactions. It is a sensitive method for identifying and quantifying trace elements in a wide range of materials, from archaeological artefacts to forensic samples.
