Extend and complement current security capabilities with rapid, sensitive and accurate detection of inorganic explosives.

The GreyScan® ETD-100™ offers the next generation in high sensitivity explosive trace detection for inorganic explosives. 


  • Highly sensitive; detects a wide range of explosives and their compositions
  • The only technology with this capability, using forensic grade fieldable Capillary Zone Electrophoresis (CZE)
  • Detects homemade inorganic salt-based explosives (nitrate, chlorate, perchlorate) used as ingredients in Improvised Explosive Devices (IEDs)
  • Complements IMS technology to addresses capabilities gap
  • Analysis time 40 seconds with a warm-up time of 10 minutes
  • Mobile and robust system – suitable for multiple fields of operations
  • Battery/mains operation
  • Low cost consumables
  • High sample throughput rate
  • Protected from overload of residual contamination
  • Highly selective, low False Alarm rates
  • Easy to use – minimum training required
  • Simple and intuitive touchscreen interface for non-expert users
  • Suitable for mobile and stationary applications
  • Capable of entry point screening and forensic lab analysis


  • Explosives detection of nitrates, chlorates and perchlorates
  • Automatic internal self-calibration
  • Limit of detection in the range of 50-100 ng
  • Sample collected on sample trap and inserted into device.
  • Method of operation via liquid phase CZE, non-radioactive
  • Sample collection using sample traps or sample wand
  • Connectivity via Serial port, Ethernet, Wi-Fi and USB2.0
  • Dimensions (W x D x H) 19.20″ x 15.20″ x 9.00″ (48.8 x 38.6 x 22.9 cm)
  • Weight 32.0 lbs / 14.5kg.
  • Power 100-240 V AC, 50-60 Hz, battery 1hr-8hrs operation (configurable)
  • Operating temperature of 40°F to 130°F (+5°C to +55°C)
  • Operating altitude of -1600 ft. to 15,000 ft. (-500 m to +4600 m), above mean sea level
  • Operating humidity of 5% to 95% non-condensing
  • Consumables are low cost sample traps, reagents, filters, verification samples

Cybersecurity Prevention by Design

The GreyScan® platform provides an appliance with a kiosk-like interface where the operating system cannot be reached under normal use scenarios. 

The ETD-100TM meets the Essential Eight which are suggestions from the Australian government to mitigate cyber security incidents, typically in an environment with servers and workstations.


Automated ETD
Advanced, automated explosive trace detection (ETD) device designed to detect homemade inorganic salt-based explosives commonly used as ingredients in Improvised Explosive Devices (IEDs).
Fast and Accurate
Provides absolute and accurate detection of inorganic explosives materials in the field and laboratory environment in 2 minutes
Automatic Protection
Fluid based and protected from overload of residual contamination. This enables no cleardown issues requiring service, which maximises uptime availability. This feature makes it amenable to the analysis of visible powder (i.e. larger than trace).
Easy to Use
Pass/Warning with audible alarms, touch screen for operation. Minimal training required for non-expert user.
