A novel, portable instrument, model NDS-2000 for the detection of illicit drugs was developed. The instrument is based on surface ionization detection system, where ionization is carried out on a heated filament. Positive ions formed in the process are drifted to a collector and a signal is registered. The front-end of the instrument consists of an integral vacuum sampler with built-in desorber system for narcotic particles. The model NDS-2000 has an internal microprocessor and LCD display, as well as visible and audible alarm indicators. RS-232 port on the instrument provides communication to an external PC for data storage and printing.
