High sensitivity and specificity

DSA Analyzer is coming

We have started to manufacture the DSA Analyzer and are preparing for mass production. For now the analyzer is available in limited volumes. While we ramp up to produce bigger quantities and sort out the bottlenecks we will manage the necessary certification programs to make sure we fulfill relevant expectations for medical devices.

Future plans

The current DSA Analyzer is a ready-to-use product for screening and detection of COVID-19, but we anticipate the product platform to expand in the future. We will continue to analyze and benchmark sensor technology to bring the best of breed to be used in our future analyzers. Buyers of the current product can still be safe regarding the investment, the future algorithms will support older device generations.

DSA Covid-19 Breath Analyzer

DSA Analyzer

Key Features

  • High sensitivity and specificity for COVID-19 recognition
  • IoT device with built-in WLAN and mobile support
  • Web-based user interface that automatically creates a unique identification for each individual breath test
  • Providing COVID-19 analysis in 2 minutes
  • No patient data needed
  • External plug-in HEPA filter in air exhaust
  • Disposable mouth piece with no-return valve


The DSA Analyzer is a handheld breathalyzer initially intended for the detection of COVID-19. The unit contains a set of carefully selected and configured nanosensors that record Volatile Organic Compounds (VOC) and biomarkers from exhaled breath. The unit communicates with a cloud-based Artificial Intelligence -powered algorithm that recognizes correlation between detected biomarkers and established characteristics of COVID-19. The unit can be field re-optimised based on any new scientific data on COVID-19. The unit is future-proof for additional disease
