Industrial e-Nose Applications

   

An e-nose is an electronic nose, a sensor that mimics the olfactory capabilities of animals and allows a quantitative identification of the vapor constituents of a sample. Until now, most attempts at e-nose sensors and systems utilized previous generation technologies such as:

  • metal oxide semiconductors (MOS)
  • conducting polymers (CP)
  • quartz crystal microbalance (QCM)
  • surface acoustic wave (SAW)
  • mass spectrometry (MS)
  • gas chromatography (GC)

Utilizing a new and proprietary MEMS-based solution, NevadaNano has developed a core technology that will revolutionize e-nose applications by offering small-size, low-cost, long-term unattended operation, and the ability to detect a very wide range of vapor types with a single sensor configuration. Electronic nose instruments are used by research and development laboratories, quality control laboratories and process and production departments for various purposes:

  • In R&D laboratories for:
    • Formulation or reformulation of products
    • Benchmarking with competitive products
    • Shelf life and stability studies
    • Selection of raw materials
    • Packaging interaction effects
  • Simplification of consumer preference test in quality control laboratories for in-line quality control such as:
    • Conformity of raw materials, intermediate and final products
    • Batch-to-batch consistency
    • Detection of contamination, spoilage, adulteration
    • Origin or vendor selection
    • Monitoring of storage conditions
  • In process and production departments for:
    • Managing raw material variability
    • Comparison with a reference product
    • Measurement and comparison of the effects of manufacturing process on products
    • Cleaning-in-place process efficiency monitoring
    • Scale-up monitoring

Application areas include Flavor & Fragrance, Food & Beverage, Packaging, Pharmaceutical, Cosmetic & Perfumes, Chemical companies. More information on Electronic Noses can be found here.
