Nexsense C Chemical Detection and Identification System

SELEX Galileo and Owlstone Inc have developed our hand-held chemical detection and identification system. This sensor is the first in the world to offer a radiation free, UHFAIMS (Ultra High Field Asymmetric Ion Mobility Spectrometry) system as a compact, hand-held device.

Nexsense C provides fast and reliable chemical detection, identification and monitoring capabilities, simultaneously for a broad, and rapidly updateable, spectrum of chemical threat agents, either CWAs or TICs.

This ground breaking technology combined with world class data processing delivers the sensitivity and discrimination required to dramatically improve monitoring, detection and identification performance over current systems.

UH-FAIMS addresses a region of a chemicals’ ion mobility response that is beyond the reach of conventional IMS systems. This enhanced data allows greater discrimination between similar chemicals, providing the Nexsense C system with the capability to clearly identify individual threat agents, and avoid confusion with common interferents.

Key Capabilities

Fast response - Continuous Monitoring with detection of threat in 10 s, Identification of detected threat in 30 s Highly sensitive – Detects threats below the IDLH level False alarms are minimised Broad-band threat spectrum - Chemical Warefare Agents (CWAs), Toxic Industrial Chemicals (TICs) and their precursors Readily expandable threat library Simultaneous - One operating mode for all threat types No Radiation Source

Technical Specifications

The system has maximum dimensions of 267 x 150 x 88 mm weighing 4.0 kg, and is designed to meet MIL Std/Spec 810.

SELEX Galileo has developed advanced algorithms that improve the sensor's discrimination capabilities through enhanced data processing and pattern recognition. This produces a reliable response to threat detection in chemically complex environments.
