Portable Laboratory

High-resolution detection capabilities of a laboratory system in a compact unit

The ETD-100

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

Inorganic compounds are being increasingly used to fabricate home-made explosive devices, due to ease of their acquisition and lack of availability of military explosives.

Governments globally are searching for forward-looking solutions that meet the changing demands of the modern threat landscape.

The GreyScan® ETD-100™ device provides accurate, sensitive and rapid detection of inorganic explosives, extending current capabilities. This device offers highly portable technology that can be used in multiple environments. Designed for continuous throughput of samples, with a rapid analysis time, this device has widespread applications for a variety of security and military applications.

The GreyScan® ETD-100™ will extend and compliment current security capabilities, providing rapid, sensitive and accurate detection of inorganic explosives.

Virus Detection TVD-1

GreyScan’s Explosive Trace Device, the ETD-100, is a result of research by leading international Universities and scientists and forward thinking investors ($25M investment to date). The ETD-100 was deployed globally in 2020 to find trace substances, preventing a host of terrorist attacks.  To GreyScan, the COVID-19 virus is a critical threat that can be detected, addressed, and prevented during a major international crisis.  

GreyScan is in the process of developing the TVD-1, using our proven technology platform to rapidly, reliably, and accurately detect the COVID-19 virus at the point of risk to human health.  We believe this device will be the first in our line of products that will be able to detect surface viruses as they evolve and spread throughout the globe.
