Outline of Final Research Achievements

I have developed an on-site screening system of drugs of abuse by a portable near infrared (NIR) spectrometer based on library search. Library search was performed after mathematical pre-treatment of the NIR spectra. Identification criteria were set based on the similarity on the hit list. This methodology enabled general screening of drugs of abuse, detection of methamphetamine over the clear plastic bags, and detection of MDMA in ecstasy tablets.
