Field TestAhura
Either Yes or No
Results
50% spill
73% unknowns
High fluorescence is biggest problem
Smith’s
Provides options
Results
50% spill
47% unknowns
False Positives

Ahura scored highest
Ahura more expensive
Had to write justificationSlide9Slide10
The Equipment
How does it work
?
Raman Spectroscopy: Molecular “fingerprint” of the molecule
Class 3B laser excites the molecular bonds and scatters measurable light to identify unknowns
ISU Ahura library- 10,152Slide11
Why the Ahura First Defender?
Currently used by law enforcement, firefighters, and the military
Very durable (4 Feet & 1 Meter)
No calibration needed-confidence check
User friendly
Ahura Customer Support- 24/7- 365 Slide12
Identification Capabilities
Drugs (illegal & prescription)
White powders
Inorganic compounds- (sulfuric acid, nitric)
Inorganic oxides- (rust, titanium

Safety
Follow your organization’s Laser Safety Protocols -Eyewear
Maintain 14” distance
Laser activated- don’t look into lens
NOT intrinsically safeSlide15
Maintenance
Cleaning
Water, alcohol, household
b
leach
Keep lens & nose cone clean
Updating
Chemical library updates
“LibBuild Mode”
Good spectrum, but no match? Export- “Ahura Reachback”Slide16
Demonstration Performance
Point and shoot through a bottle?
No problem!
