Abstract

The Narcotics Detection Technology Assessment (NDTA) program is a series of studies conducted to evaluate illicit substance detection devices. The ability to effectively detect cocaine and heroin particles is directly related to the efficiency of a detection device's sample collection design. The NDTA tests are therefore structured to require sampling of narcotics from a surface. Tests standards are required which permit subnanogram to microgram quantities of narcotic to be dispensed onto a target surface for sampling. Optimally, the standard should not adversely affect the performance of the device under test. The NDTA test team has developed and experimentally characterized solution- deposited substrate standards, solution-deposited substrate- free standards, vapor-deposited standards, suspension standards, and dry mix standards, and dry mix standards. A variety of substrates and dry-mix fillers have been evaluated, including sand, fullerenes, copper powder, nickel powder, pulverized paper, and aluminum. Suspension standards were explored with a variety of liquids. The narcotic standards with the best performance were found to be dry mixes of cocaine with silver-coated nickel powder, and dry mixes of heroin with silanized glass beads.
