Breathing Gas Analysis

Respiratory Gas Analysis by integrated surface solution without device assistance

The respiratory gas mask can be converted into an elegant test system for non-invasive analysis of the respiratory gas. As this test system is also suitable for sampling over a longer period of time, an adjustable concentration of the analyte over the wearing time is possible.

  • Non-invasive analysis of organic compounds (cytokines, proteins, bacteria)
  • Analysis system made of functionally integrated cellulose surface
  • Modified cellulose with high mechanical stability, flexibility & water absorption capacity
  • Combination of sample collection, sample concentration & analysis


Possible applications:

  • Infection diagnostics
  • Respiratory diseases (e.g. COPD)
  • Clinical and forensic drug testing
