Abstract

ThermoFisher Scientific (formerly Ahura Scientific) has developed a handheld, modular detection and identification system for trace-level gases, chemical vapors and aerosols, and swab analyses. The sample chamber is a separate, removable module that can be tailored specifically to the users’ needs. The vapor module can operate in three modes: ambient sampling, vapor/aerosol preconcentration, and direct injection. A swab module can be used to analyze thermally desorbed vapors from a sample swab. Limits of identification for vapors are as low as 0.1 ppm following a 15-min preconcentration period. The swab module can detect as little as 5 μg of TNT.
