zNose® by EST
Supplied and Supported by TechMondial. Electronic Sensor Technology Inc. (EST) has revolutionized chemical vapour analysis with its patented zNose® technology.
This breakthrough system combines rapid gas chromatography (GC) with advanced detection capabilities (SAW), enabling precise trace analysis of volatile organic compounds (VOCs) across a wide range of applications, including:
- Homeland Security
- Life Sciences
- Chemical and Petrochemical Industries
- Food and Beverage
- Environmental Monitoring

Why zNose®?
Unmatched Sensitivity and Speed. The Model 4600 zNose® offers real-time volatile organic compound (VOC) detection and analysis with parts-per-trillion (ppt) sensitivity. It excels in both qualitative and quantitative assessments, making it indispensable for industries requiring exceptional precision and efficiency.
Applications Across Diverse Industries
- Chemical Analysis: Detects VOCs in chemical and petrochemical processes with unparalleled speed and accuracy.
- Plastics: Evaluates VOC emissions in production and packaging environments.
- Fragrance and Odour Management: Produces olfactory images for precise aroma chemistry analysis.

Powerful Detection for Security and Research Applications
The zNose® is the first electronic nose designed specifically for security purposes, delivering ultra-fast GC to identify chemical vapours associated with explosives, biological hazards, and other threats.
Advantages Over Traditional Methods:
- Eliminates the need for slow, swab-based analysis typical of IMS technology.
- Detects concealed threats that may evade standard surface sampling techniques.
- Offers rapid, real-time analysis even in high-traffic areas like airports and border checkpoints.
Portable Design
Compact roller case with detachable sampling nose for maximum flexibility.
Remote Sampling Kit
Enables inspection of hard-to-reach areas like ventilation ducts.
Real-Time Results
Delivers ppt-level sensitivity for precise, near-instantaneous detection.
