Abstract

In the field of anti-illicit drug applications, many suspicious mixture samples might consist of various drug components—for example, a mixture of methamphetamine, heroin, and amoxicillin—which makes spectral identification very difficult. A terahertz spectroscopic quantitative analysis method using an adaptive range micro-genetic algorithm with a variable internal population (ARVIP¿µGA) has been proposed. Five mixture cases are discussed using ARVIP¿µGA driven quantitative terahertz spectroscopic analysis in this paper.
