The BreathSpec has been designed for the analysis of VOC (Volatile Organic Compounds) metabolic profiles in human breath. This instrument would be ideal for clinical applications where non-invasive patient screening is valuable to aid the clinician decision making process, determining different treatment or monitoring paths and outcomes.

  • Non-invasive analytical instrument
  • Extremely easy to use easy to analyse data
  • Extremely sensitive, with detection levels at low ppbv or even pptv level
  • Integrated with spirometry for simple, safe and approved breath sampling
  • Reproducible analysis through highly advanced sample handling (patent pending)
  • Very fast analysis with results available within minutes
  • Low maintenance, runs at atmospheric pressure, internal gas re-circulator (no separate gas supply needed)
  • Ability to build metabolite databases and characterise peak profiles
  • Principal Component Analysis (PCA) integrated functionality
