Sniffing Out Trouble In Real Time

Summary: The Detection and Quantification of Airborne Substances
via Real-Time On-Site Analysis is Now Possible With QualSec's
Nano-Nose
NORTH LOGAN, Utah--(Business Wire)--
QualSec (OTC: QLSC.OB)--Electronic noses have been used for years
in the laboratories of NASA and other organizations. However, until
now they have been impractical for use in the real world. Electronic
noses have lacked portability, taken too long to produce useful
results and have only been able to analyze lab-prepared samples.

Enter QualSec's Nano-Nose.

The Nano-Nose will revolutionize the electronic nose industry with
its compact size and practical applicability. The lightweight device
is hand held, and can detect and quantify analytes instantaneously.
The Nano-Nose is also unique in its ability to analyze streaming air
rather than just lab-controlled air samples, amplifying its real-world
usability.

QualSec's CEO J.E. Hand states "all other industry efforts to
develop an e-Nose use some form of gas chromatography or rely on
carbon polymer chips to react to a VOC. These approaches are
fundamentally flawed because:

They require pre-concentration of air samples;

Can only test for the presence of a VOC;

Are less reliable when exposed to heat or moisture;

Require training of operators and recalibration of sensitive
equipment;

Are effected by heat, moisture, and are only reliable in near
laboratory conditions.

While others are attempting to shrink and transform existing
laboratory equipment for field use, QualSec has approached the problem
from a new vantage point, utilizing previously unconsidered
nano-technology. QualSec's Nano-Nose has the capacity to finally meet
the air detection needs of many markets, including the homeland
security, food and beverage, environmental protection and health care
industries.

QualSec CEO Hand quipped, "Everyone else is trying to make their
go-carts run faster, whereas QualSec offers a fully loaded luxury
vehicle. "
