zNose EST 7100 - Benchtop

The vapor detector and analyzer identifies vapors as low as parts per trillion concentrations and amounts less than 50 picograms. A proprietary Surface Acoustic Wave (SAW) detector results in a system with previously unattainable sensitivity in a portable low-cost package.

Can analyze vapors in 10 seconds with sensitivity in parts per billion for many compounds

Detects hydrocarbons in the range of C4 – C25. Sensitivity will vary by compound, sampling time, matrix, interferences and detector temperature settings.

Compound Identification is possible using a library of Kovats Indices

• Allows rapid and reliable recognition of odour characteristics
• Measure freshness, spoilage, desirable and unwanted odours
• The only electronic nose system validated by the US EPA
• Use as a highly sensitive, portable, fast GC or "ZNose"
• Exceptional speed (10 second chromatography)
• Fully quantitative, easy calibration
• Measures to picogram/ppt levels
• No need for autosamplers
• Direct sampling of environmental gas and food odours-more sensitive than the human nose
• Use as a highly sensitive Surface Acoustic Wave sensor and short GC capillary column
• Dedicated software to optimise sample recognition and methods development
• No need to correct for sensor drift
• Sensor overlap and interference reduced dramatically
• No interference from water or alcohol
