| Research International, Inc. - RSN 5100

General Description
The Remote Sensor Node 5100 (RSN 5100) is a field-portable instrument system that uses multiple technologies to monitor for the presence of chemical, biological, radiological and nuclear threats. It is the only product of its kind currently available in the world, integrating detection technologies from the world's leading suppliers into a complete, networked CBRN monitoring solution. It has been developed for use in military, homeland security, public safety and public health applications. The RSN 5100 is modular in design and can be configured with all or just some of the sensor subsystems depending on customer requirements.

Available sensors include:

State-of-the-art chemical detectors
An ultraviolet fluorescence-based biological particle detector for suspicious changes in bioaerosol concentrations.
A sensitive gamma ray detector that detects suspicious changes in background radiation.

If alarm levels are exceeded, a secondary air sampling circuit is automatically activated to collect a permanent aerosol particle sample onto a special high efficiency filter element. Any particulates collected can then be analyzed with a portable or laboratory-based biological, chemical or radiological system.

Technical Description
The RSN 5100 normally operates in a background monitoring mode. In this condition it samples air at 2 liters/minute. The air stream is analyzed with anion mobility spectrometer to detect and identify chemical warfare agents. It is further analyzed with an array of 6 electrochemical gas detectors for common toxic industrial chemicals. A gamma ray monitor is used to detect radiation in the air sample. Finally, this air sample is tested for suspicious increases in bioaerosol concentration with the TacBio bioaerosol monitoring instrument. This device passes the air stream through an optical chamber where particulates are irradiated with 365 nm light. Both fluorescence signals and photon scattering events are collected and analyzed to look for an increase in biological particle concentration. If an instrument alarms (or under remote control), an embedded air sampler, based on the SASS 3100, is turned on which collects particulates at 300 liters/minute onto a proprietary electret filter for later analysis of captured biological or other particulates.
