3. What is the HAZMATCADTM?
The HAZMATCAD™ is a next generation handheld trace chemical agent detector for Nerve (G) and Blister (H) agents as well as Hydrogen Cyanide (AC) or Phosgene (CG). The HAZMATCAD™ is designed to detect for these warfare agent gases with minimal interference from other chemicals which are often present in the battlefield or urban environment.

5. What is the HAZMATCAD™ Plus?
The HAZMATCAD™ Plus expands the performance of HAZMATCAD™ by adding the ability to detect selected TICs (Toxic Industrial Chemicals). These chemicals are detected and reported by class identification (hydride and halogen gases).

6. HAZMATCAD™ Configurations
HAZMATCAD™ Plus
SAW (nerve and blister)
Four electrochemical cells (blood, choke, halogen and hydride gases)
HAZMATCAD™
SAW (nerve and blister)
One electrochemical cell (blood or choke)

7. False Alarms vs. Analysis Time
Fast Response Time – IMS – Typically (5 to 30 sec)
Direct readout of total contamination
No sample pre-collection or clean up
Increased risk of false positives
HAZMATCAD™ Analysis Time – SAW (20 to 120 sec)
Fast Mode (20 sec) or High Sensitivity Mode (120 sec)
Sample collection on absorbant media
Sample control
Reduced risk of false positives

8. How Does a SAW Sensor Work?
Small Piezoelectric Crystal
Interdigital Array
Polymer Surface Coating
RF Electronics to Drive SAW
Data Collection - frequency changes as mass absorbs into polymer
