Term: Surrogate Compound
Definition: A surrogate is a compound added to a sample to evaluate the performance of an analytical method and its ability to recover the analyte of interest.
Term: Extraction Efficiency
Definition: Extraction efficiency refers to the effectiveness of a process in recovering a specific analyte from a matrix, which can be affected by factors like the matrix type and characteristics.
Term: Calibration
Definition: Calibration is the process of adjusting analytical instrument responses based on known standards to accurately quantify unknown samples.
