The technology of zNose® is patented and employs a proprietary “Surface Acoustic Wave” (SAW) sensor and ultra-fast "Gas Chromatography" (GC) technology which specializes in separating vapor samples according to their chemical and physical properties.
SAW sensors used in the zNose® are special, uncoated chemical vapor sensors that identifies chemicals based on the retention times of the chemical in GC Column. The sensor, with resolution down to parts per trillion, allowing for the creation of a sensitive "lab on a chip".
GC is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. zNose® employs an ultra-fast Gas chromatography technology that enables it to separate chemicals within an odor in near real time.
VaporPrint™ Images and Pattern Recognition is a polar plot of chromatogram time with the radial direction being the sensor signal or the derivative of sensor signal. With VaporPrint™, zNose® provides an important graphical feature well suited for Electronic Nose pattern recognition algorithms.
Why zNose®?
zNose® is highly sensitive in detecting even the most concealed compounds. No other electronic nose comes with a library of more than 700 chemicals and odor signatures. Moreover electronic noses that are mainly used for detection of various chemicals don’t use ultra-high speed chromatography to separate chemicals. The Electronic Sensor Technology's flagship product has been developed with a number of key capabilities that differentiate it from the other products in its category.
There is a big list of reasons why zNose® is the most trusted instrument in the market today.
Recognizes odors and fragrances based on their full chemical signature
Detects all compounds within an odor and provides a full chemical profile
An expandable library of 700+ chemicals and odor signatures
Ultra-high speed chromatography to separate chemicals within an odor in near real-time
Pattern recognition and trace detection can be performed at the same time
Next Global Security Threat – Bioterrorism

The future of international security will be fought on the biological front. Rapid advances in genetic engineering have opened the door for small terrorist groups to tailor and easily turn biological viruses into weapons – bioterrorism. A resulting disease pandemic is currently one of the most deadly threats faced by the world, yet governments are complacent about the scale of the risk, claimed Bill Gates, in an address to the Munich Security Conference, a global forum for discussing security problems.
Gates warned about the dangers of a bioterrorist attack that could wipe out 30 million people in less than a year and how we’re not prepared for it. “We ignore the link between health security and international security at our peril,” reported futurism.com.
Gates, whose charitable foundation is funding research into quickly spotting outbreaks and speeding up vaccine production, said the defence and security establishment “have not been following biology”.
He said developments in genetic engineering were proceeding at a “mind-blowing rate”. Biological warfare ambitions once limited to a handful of nation states are now open to small groups with limited resources and skills.
He said the potential death toll from a disease outbreak could be higher than other threats such as climate change or nuclear war.
“With nuclear weapons, you’d think you would probably stop after killing 10 million. Smallpox virus won’t stop. Because the population is naïve, and there are no real preparations. That, if it got out and spread, would be a larger number.”
The increasingly common use of gene editing technology would make it difficult to spot any potential terrorist conspiracy, according to telegraph.co.uk.
Speaking ahead of the address to the Munich Security Conference, Gates said one of the most potentially deadly outbreaks could involve the humble flu virus. It would be relatively easy to engineer a new flu strain combining qualities from varieties that spread like wildfire with varieties that were deadly.
Gates argued that the key to preparing for such a situation is building an arsenal of new weapons — vaccines, drugs, and diagnostics — and cutting down the time it takes to prepare them. Vaccines can be especially important in containing epidemics. But today, it typically takes up to 10 years to develop and license a new vaccine. To significantly curb deaths from a fast-moving airborne pathogen, we would have to get that down considerably — to 90 days or less. […] The really big breakthrough potential is in emerging technology platforms that leverage recent advances in genomics to dramatically reduce the time needed to develop vaccines.
