Märgistusaine

Märgistusaine, often translated as a marker substance or tracer, is a compound that is added to a substance or system to allow for its tracking, identification, or quantification. These substances are typically introduced in small amounts and are designed to be detectable through various analytical methods without significantly altering the properties of the main substance or system. The choice of märgistusaine depends heavily on the application and the detection method available.

In environmental science, märgistusained are used to study the movement of water in rivers, groundwater, or the atmosphere. They can help determine flow rates, identify sources of contamination, or understand mixing processes. For example, fluorescent dyes are commonly used in hydrology. In industrial processes, märgistusained can monitor the flow of materials through complex pipelines or identify leaks.

In medicine, märgistusained, often referred to as tracers, are crucial in diagnostic imaging techniques like PET scans or SPECT scans, where they are administered to patients to visualize organ function or detect abnormalities. In food industry, they might be used to verify authenticity or track the origin of products. The key characteristic of a märgistusaine is its distinct and detectable signature, allowing it to be easily distinguished from the surrounding environment or the primary substance it is mixed with. Safety and non-toxicity are often paramount considerations, especially in applications involving biological systems or consumption.
