- VOC Analysis Instruments


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
