Trace Analysis is a scientific method used to detect and analyze small amounts of substances, often referred to as traces. This technique is commonly employed in fields like forensic science, environmental monitoring, and materials science to identify chemical compounds or contaminants in various samples, such as soil, water, or biological materials. The process typically involves collecting samples and using specialized instruments to separate and quantify the trace elements present. By examining these traces, researchers can gain insights into the composition of materials, identify pollutants, or even solve criminal cases by linking evidence to specific sources or individuals.
