Press Release Summary: The Detection and Quantification of Airborne Substances via
Real-Time On-Site Analysis is Now Possible With QualSec’s Nano-Nose.

Press Release Body: NORTH LOGAN, Utah -- (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;
*They can only test for the presence of a VOC;
*They are less reliable when exposed to heat or moisture;
*They require training of operators and recalibration of sensitive equipment;
*They are affected 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. “
