Trace analysis is the study and interpretation of small quantities of substances or particles to gather information about their origin, composition, and history. It is crucial in fields like forensic science, environmental monitoring, and materials science, where it helps to identify sources of contamination or provide evidence in criminal investigations.
The Limit of Quantitation (LOQ) is the lowest concentration of an analyte that can be quantitatively detected with acceptable precision and accuracy under specified conditions. It is crucial in analytical chemistry for ensuring reliable measurement results, especially when working with trace levels of substances.
Runtime Verification is a lightweight formal method used to ensure that a software system adheres to its specifications during execution by monitoring its behavior in real-time. It provides a practical approach to error detection and system assurance, complementing traditional testing and static verification techniques by addressing the limitations of each.
Material purity refers to the degree to which a material is free from contaminants or impurities, which can significantly impact its properties and performance. High purity materials are essential in industries such as electronics, pharmaceuticals, and metallurgy, where even trace impurities can lead to failures or inefficiencies in processes and products.
Isotope dilution is a quantitative analytical technique used to determine the concentration of an element in a sample by adding a known quantity of an isotopically enriched compound. This method enhances accuracy by compensating for sample loss and matrix effects during analysis, making it highly reliable for trace analysis in complex matrices.

Impurity refers to the presence of unwanted substances or elements within a material, which can significantly alter its properties and behavior. Understanding and controlling impurities is crucial in fields like chemistry, materials science, and pharmacology, where purity directly impacts the efficacy, safety, and performance of products.
Parts per million (ppm) is a unit of measurement that describes the concentration of one part of a substance in a million parts of another, typically used for quantifying trace amounts in environmental science and chemistry. It provides a way to express very small concentrations, such as pollutant levels in air or water, where precision is crucial for safety and regulatory compliance.
